Looks like some physicists are trying to apply an optical multiplexing trick to add another dimension to modulating RF waves:

This wave property differs from circular polarization and is visualized below:

How the heck could you design the transmit and receive antennas to differentiate integer modes? What about RF front ends?

I'm skeptical of this. I see a lot of European scientists putting out such things as faster than speed of light transmission, ways of violating Einsteins relativity, and "cloaking breakthroughs", and yet it never comes to fruition.

Anyway, I don't see this being used in any manner anytime soon.
