I believe that they are doing is to use some polarized material such as a
piezoelectric crystal, type what we have in any crystal for frequency control.
A vibration (which we always have when we are using a crystal) will not shaking
the electrons but also the charged protons in the nuclear core. Maxwell's
theory does not require an electron but an electric charge to generate a radio
wave. What I don't know is whether quarts crystal is emitting RF radiation or
not.
All we can do, unless we are involved in this research is to sit down, wait and
enjoy the show.
There are already small antennas available, commonly used in cellphones. They
rely on a (I believe) a piezoelectric dielectricum to make the small size
possible.

Hmmmm.
Me, I read far enough to see that the paper wasn't published on April
1. Since it wasn't, I went back to watching Sponge Bob Square
Pants.

Much Smaller Antennas Possible?
My first thought on this is "there is no free
lunch". I have not yet read the paper, and do not understand what they call
"symmetry breaking". However, there are two things that limit the performance
of physically small antennas. First, power density is defined as power per unit
area. This means a small capture area will capture a small amount of power.
Second, physically small antennas usually mean small impedances. That means
high currents and high I^2*R losses.
Superconducting antennas can get around
some of these losses at the cost of high complexity.
The basic concept of an
antenna is matching an electrical circuit to free space impedance. Dielectric
antennas are well known and often used in UHF and above antennas. The purpose
of the dielectric is to make the wavelength physically smaller for a given
frequency by a proportionality constant known as the dielectric constant. This
tends to concentrate the field in the dielectric, making the loss tangent of the
material important.
Since the time of Newton, we have known that differing
dielectric constants bend photons at interfaces between different dielectric
constants. (Radio is just long wavelength photons.) So changes in dielectric
constant tend to reflect and refract the waves unless carefully engineered to
pass them efficiently.
This concept appears to be trying to apply some
quantum effects to radio wavelengths. We already do this with lasers. Light is
emitted at a specific wavelength when an electron transitions from one energy
level to another. This appears to be a mechanical analog of this process.
This would allow a physically small device to emit coherent energy.
I will
follow up after I have read the paper to see if there is anything useful
here.
