Bioelectromagnetics Part 1: A Little Physics

(This article isn’t final, it’s just a public preview, so it might contain some small mistakes.)

Working with invisible fields of energy is a tricky business: you can’t really see what you are doing unless you have a device to make it measurable. Mainly because of this, energy medicine (the methodology to do health readings and to provide health benefits using invisible fields) is still a controversial subject.

Healing with energy fields can divided into two categories: energy healers (when a human accelerates the healing of another) and radionics (when a machine generates certain waves to help the patient heal). I will focus on the second one which is also known as electromagnetic therapy.

We are going to explore the electromagnetic fields around living beings and their interaction with other such fields. Science calls the study of these phenomena “bioelectromagnetics”.

Part 1: A Little Physics

First of all, we have to be honest about the title of the post. As Sheldon Cooper well said in the show “The Big Bang Theory”, there is no such thing as “little physics”. Physics encapsulates the entire Universe from quantum particles to supernovas, from spinning electrons to spinning galaxies.
I will focus on a few definitions which are important for us to understand the phenomena of energy detection, energy transfer and potentially energy healing.
If you feel confident about wave theory and basic electrical engineering you can skip ahead and check out Part 2. This is not a physics course by any means, I will simplify things drastically. If you have questions, you can always ask them in the comment section, or check out Khan Academy’s Physics and AC circuits sections.

Waves and fields

Energy medicine is all about waves and fields.
Electric fields surround electric charges (like the current flowing in your electronic devices), magnetic fields surround magnetic materials (like magnets).
The field is simply a name for a space where electronic and/or magnetic interaction takes place. Interestingly enough, no matter how small an electric charge is, its field expands into infinity.
The more sensitive our detection mechanism is, the further away from the charge can we detect its field.
If an electric field strength doesn’t change over time, we call it electrostatic field, if it changes it’s called electrodynamic field.

With our current technologies we can produce an electromagnetic field (a combination of electric and magnetic field) which changes over time as we wish. By changing the charge or our field source we can generate certain patterns and we call these waves. These waves, these changes in the field can be then detected at a remote location if we know what pattern we are looking for.

If we connect the transmitter and the receiver with a solid conducting material, we call it a wired communication, if we don’t then we call it wireless communication. In the wireless case we usually design antennas (specially formed conductive materials) for both the transmitter and receiver to make the communication more efficient.

The electromagnetic waves are fascinating and we could endlessly discuss their wonders, but I would like to focus on just three of their properties here: waveform, amplitude and frequency.

Waveform, amplitude, frequency

The pattern we use when we change the charge we call waveform. These are usually periodic, so depending on the form of the repeated pattern we called them sine, square, triangle or sawtooth. We can always create our custom form, these are just the more commonly used ones. You can typically find the sine waveform in nature and analog devices, and the square waveform in our digital gadgets.

Every pattern has a maximum and a minimum charge value. Between that two values we can measure the charge distance, the so called peak-to-peak voltage (number 2), and its amplitude is the half of that (number 1) in the case of a sinusoidal wave.

As we now know these waves change over time. How quickly they repeat their change-pattern is defined by its frequency (defined with the physical units of Hz, cycles per second).
If we repeat one pattern every second, we would say this wave is a 1 Hz wave, if it repeats that pattern 5 times per second, we would say it’s a 5 Hz wave, etc.

The Electromagnetic Spectrum

Let’s say we have a generator device that generates a bunch of sine waves at different frequencies. We have another device, the receiver, where we are trying to figure out at what frequencies the generator work with.

The receiver gets the combined signal and then it transforms that signal into a form, where the intensity of every signal component can be inspected separately. This is called the signal’s spectral density or spectrum.

There are plenty of wave generators in nature. Some use lower frequency waves, some use higher frequency waves. There is no limit how low or how high a frequency can be, so nature’s spectrum is infinite.

From the practical standpoint it was important for us humans to define certain sections of this spectrum and name them depending on the usage of those waves.

If you look at the chart below, you can see that we use these electromagnetic waves for our TV and radio broadcasting, to heat our food with microwaves, to generate thermal images or to create X-ray photos of our bones.

Interestingly our eyes are wave detectors as well: there is a tiny section of this spectrum what we can detect with our eyes, and the different frequencies are processed and represented as different colors in our brains.

What absolutely mind-boggling is that everything we know, every material interacts with this spectrum in one way or the other, all the time. You are – as a human being – swimming in these waves 24/7 and you reflect or refract these waves depending on your current state and the waves we investigating.

For example, if you are wearing a red sweater that looks red for you only because that sweater reflects red and refracts/absorbs all the other from the visible spectrum. But it’s not just you and your sweater, its everything around you!

Resonance

Resonance is the phenomena when an object oscillates at a given frequency with the highest amplitude. This is a property of the object, so every object has a resonant or natural frequency. This frequency is the product of the object physical geometry.
If two objects have the same or very similar resonant frequencies then if you stimulate one of them then all the others in close proximity will start vibrating as well.

Lasers are special light-wave sources that emit light waves at one particular frequency. If I use for example a 635 nm/472 Ghz red laser to beam light on an object and I somehow measure the amount of the reflected red light waves, then I am able to build that object’s frequency response at that particular 472 GHz frequency.
If I stimulated that object with many different laser beams (at their different frequencies) I would get multiple reflection values at those testing points.

To describe any system’s ability to respond on any particular multi-frequency stimulus we can define the systems “frequency response”.
The device which is able to cover a particular frequency range and create a target’s frequency response is called the frequency response analyzer. It would produce a chart at the end, similar to this one:

Don’t worry about the details of this chart yet, first we will go through some of the electronic parts of such an analyzer in order to understand how are we exactly measuring the response values

Frequency Response Analyzer

So, first, we need a signal generator. This will generate our signal at a particular frequency by using a DAC (digital to analog converter) and direct this signal towards the DUT (device under test) probably with an antenna or electromagnet. This will generate a field at the measured frequency with a given amplitude.
Secondly we need a receiver. This is an antenna and a ADC (analog to digital converter). This ADC is able to convert the analog signals detected on the antenna into digital signals which we can use later for processing without data loss. The amplitude of this detected signal is the critical value we want to measure. We can be sure that some weakening of that signal will be present just because of the fact that it needed to travel the electromagnet – air – device – air – antenna distance while all of these components interacted with that signal.

At this point we have a analog signal strength at the output of our DAC and another analog signal strength on the input of our ADC. If we compare the two we get one frequency response value at the tested frequency.
If we now change the frequency just slightly on our DAC and ADC we will have a new value. If we repeat this many times at different frequencies, we will get our chart (just like above), the frequency response chart of the DUT.
By the way, this DUT could be anything, from a simple salt crystal, through a human body, to our whole planet

The chart itself shows the attenuation (y-axis) of the electromagnetic waves at certain frequencies (x-axis). Attenuation is an expression to define the ratio of the input intensity from the DAC and the output intensity to the ADC in our case.
Interestingly this ratio is measured in dB (decibel) which is a little bit difficult to wrap our minds around, because it’s a logarithmic unit. To put it simply if you see that the attenuation is 0 dB that means that the input and the output is the same, the signal propagated perfectly. If the attenuation is -20 dB then the output signal’s amplitude is 1/10th of the input signal. If it’s -60 dB then the output is 1/100th of the input. Don’t worry, it’s not that critical at this point, you can get used to it later with practice.

Electronics

Now, in order to understand how energy healing could work, we need to investigate the electronics, the devices we use today especially the ones which interact with the human body in some shape or form.

Every electronic device needs a power source to work. It can be so called direct current (DC) or alternating current (AC). Our batteries have DC, our power outlets have AC. The main difference between the two is that AC changes its voltage constantly as a given rate, just like the sinusoidal waves we mentioned above. Both DC and AC have their advantages and disadvantages.
To convert the AC of the power outlet to DC, which is typically more useful for electronic devices, you need an power adapter.

Let’s say you pick an AA battery from the supermarket. It has a plus and a minus conductive end. The potential difference between the two ends of the rod is 1.5V (Volts). If we wanted to have a very basic DC circuit, we’d connect a load (for example a light bulb) to the battery. It will emit light and the reason behind this phenomena is that the wire inside the bulb starts to heat up. Depending on the material you use here, it takes a certain amount of electricity to move that electricity through it, and this property is called the resistance of the material. The bigger the resistance, to more energy is needed to move the electrons in that material and more energy is wasted (as heat) through transport.

We have a similar, but slightly more complicated situation with AC circuits. If our source is AC (like the power outlet) and we wanted to transport that energy somewhere, our transportation medium (like a wire) will have something similar to resistance, but it’s called impedance.

Resistance and impedance

Both resistance and impedance have the physical units of Ohm, but resistance is a scalar, impedance is complex number. As you probably know complex numbers have a real and an imaginary part.
I know it’s getting a little scary here, but bear with me, we are almost finished with the physics part! 🙂
So, since we are going to work with AC in energy medicine, it’s important to understand that the impedance of a (biological) system at a certain frequency tells us how well that system forwards a particular signal through itself (that’s the real part), and how much it changes the phase of that signal (that’s the imaginary part). The phase shift simply means how much the current change lags the voltage change.

Simply put: if we want to understand a system better, we need to measure its impedance at different frequencies, so that we can calculate its frequency-response property for both magnitude/amplitude (real part) and phase angle (imaginary part).

When we use this method on a biological system (like the human body) we call this bioelectrical impedance calculation of the system.

Building an X-ray machine

Alright, let’s put our knowledge into practice! How would we build an X-ray machine?

First of all, we would need a signal generator. This would be the source of our X-rays, which are just normal sinusoidal electromagnetic waves in the frequency domain somewhere between 30 PHz and 30 EHz. If we want to make an analogy with photography which operates in the visible light frequency domain (430-750 THz), the signal source would be our light source.

To make an X-ray photo, we would need a signal detector, just like a photo camera if we were taking a normal photo. In the case of digital cameras they have a small circuit called the CCD (charged coupled device). This circuit has many many small detectors of visible light. Those detectors can measure the intensity of the light at 3 particular frequencies, one for red, one of blue and one for green. In the case of our X-ray machine, we need something similar, but specialized to detecting X-ray waves.

The name of such a detector array is called a Flat Panel Detector (FPD). The sensors are arranged on a two dimensional grid and they continuously measure how much X-ray hits them. Those values are sent to a digital processing unit to finally generate a grey-scale image. Every pixel can represent a sensor, the brighter pixels representing more absorption of the X-rays by the body. Bones are particularly good absorbents of X-rays because of their calcium content.

Now that our X-ray machine is done in theory, we can see that the active night-vision goggles work in a similar way: they have a shortwave infrared (SWIR – 100–214 THz) or near-infrared (NIR – 214–400 THz) signal generator and their appropriate CCD detectors built-in into the goggles.

The composition of radar, MRI, CT, Ultrasound are also very similar as we will see later. They are all extending our senses to detect electromagnetic waves outside of the ranges of our eyes and convert them into the visible spectrum in one way or another.
