In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics ...

The rotational Doppler effect based on the radio orbital angular momentum (OAM) carrying wave has been theoretically studied and experimentally verified at 10 GHz. By using the higher-order OAM mode ...

Orbital angular momentum (OAM) mode multiplexing has the potential to achieve high spectrum-efficiency communications at the same time and frequency by using orthogonal mode resource. However, the ...
