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 ...

In this paper, we design a 38 GHz orbital angular momentum (OAM) antenna consisting of a horn antenna, a spiral phase plate (SPP), and a biconvex lens. The results show that this antenna design scheme ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...
