>So it's the electromagnetic field waving/in motion

not exactly
a 'wave' if we're not talking about the synchronized waving of arms at a football stadium is a complex subject.
Generally a wave is a localized change in potential that is usually periodic but doesn't have to be (soliton waves)
Electromagnetic waves are composed of both electric field component potential changes and magnetic field component potential changes simultaneously. And in the free space form that most are taught about these waves propagate away from the radiating source in a straight line (unless reflected or refracted) with an attenuation of 1 / distance3. A guided / bounded wave may travel thru a waveguide with an attenuation factor less than 1 / distance. As you can see a guided / bounded wave has a huge advantage in transmission losses.

The peculiar part about guided waves or bounded waves ie. waves propagating thru a 'waveguide' is there are conditions that will cause one or both components (electric and magnetic) of the wave to be insensible, almost as if it was folded into another dimention. TE (transverse electric) mode waves, TM (transverse magnetic) mode and TME (transverse magnetic electic) mode.

during the TE mode when a wave is propagating thru a waveguide the electric field component travels on the inner surface of the waveguide as a zennek wave

The space between the Earth and Ionosphere make a giant concentric spherical waveguide. These people (ViZiV) propose to exploit this in much the same way that Nikola Tesla proposed to do. They use slightly different language to describe the same phenomena.

Time will tell, as this time the project has the baking of people who have much better business sense than Tesla did 100 years ago.
