Detecting the Orbital Angular Momentum of Electro-Magnetic Waves Using Virtual Rotational Antenna
Abstract Orbital Angular Momentum (OAM) is a typical spatial mode of an Electro-Magnetic (EM) wave. Correctly detecting the OAM mode is fundamental and of foremost importance when applying the phenomenon to wireless transmission in free space. It is found that when rotating an OAM wave, a rotational...
