I don't know about the protection value of the gizmo in question. I couldn't understand the science-fu.
However, it did prompt me to try to work out a few basics.
The idea that all objects have a resonant frequency, measured in Hertz, is nothing new. If a signal is emitted, and a nearby object shares a resonant frequency, it absorbs energy and starts to vibrate with greater amplitude, (in the case of a guitar string, this would be "louder").
If a calcium atom, (or "ion") has a resonant frequency matching a radio source, then it too will pick up energy and vibrate with more energy, changing how it behaves and interacts within biological systems.
Okay.
So.., I tried to verify what the resonant frequency of various ions were.
That's not easy to do! The great internet is rarely asked this particular question, and when it is, responders don't really know how to answer it, or if they do, they use units of measurement which are difficult to translate into hertz.
So I started off simple: Hydrogen. The humble "H" atom! Surely we must know the resonant frequency of the hydrogen atom?
Well, probably we do, but it's not quite so simple as asking Google. (Try it. Maybe you'll have better luck than me.)
For instance, Wikipedia has this to say about the
hydrogen mazer - (different from a
laser in that the emitted beam is not visible):
[...] In both types, a small storage bottle of
molecular hydrogen, H2, leaks a controlled amount of gas into a discharge bulb. The molecules are dissociated in the discharge bulb into individual hydrogen atoms by an arc. This
atomic hydrogen passes through a
collimator and a magnetic state selector. The atoms are thereby selected for the desired state and passed on to a storage bulb. The storage bulb is roughly 20 cm high and 10 cm in diameter and made of
quartz. Its inside is coated with
Teflon, allowing many collisions of the atoms with the wall without perturbation of the atomic state, and slowing the recombination of the hydrogen atoms into hydrogen molecules. A durable Teflon & bulb coating technology allows for over 20-year lifetime.
[3] The storage bulb is in turn inside a
microwave cavity made from a precisely machined copper or silver-plated ceramic cylinder.
This cavity is tuned to the 1.420 GHz resonance frequency of the atoms.[
Okay. But 1.420 GHz is waaaaaaaay beyond the frequencies studied in the paper quoted in original post of this thread looking at cyclotron resonance in regard to Calcium;
"one was close to 7 Hz and the other was close to 50 Hz".
That's orders of magnitude different. And I'm guessing that the Calcium ion is probably not so different in its resonant frequency from that of Hydrogen. But I don't necessarily doubt the claims; I think it's far more likely that I'm simply not understanding something.
-In fact, I ran across the idea of Cyclotronic Resonance many years ago, in discussions about the
Lithium ion, and the active number where biological effects were seen was at 60 Hz. The effect observed being that in conjunction with wall socket electrical frequencies (60 Hz) and the Earth's Magnetic Field, any free Lithium ions in the blood of the subject energizes and mobilizes, and becomes more medicinally active. Lithium is used in anti-depressant drugs, and mice or rats or whatever creature being studied indeed became measurably slower when exposed as compared to controls.
But 60 Hz again is waaaay below the resonant frequency you'd probably need to energize Lithium gas in a laser-type system. It's probably up in the gigahertz region as well, I'd guess.
So... what gives?
Are we talking about some other aspect of these atoms which vibrates?
Other issues complicating includes the fact that the gas pressure a cloud of ions is stored at changes the resonant frequency. (I found a great paper on that which was a morass to wade through, but I could sort of understand and pick some useful things from. It's a lovely old text written back when science was more honest and straight forward. You can look at it here:

Though one thing which does stand out in all of this...
The gigahertz range is exactly where the new 5G systems are expected to operate; within the same resonant window that fundamental atoms and presumably molecules live.
Just some thoughts from a science noob with the power to read books and scratch his head and ask sensible sounding questions, but who is usually just further confused by the answers.
