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 ...

With the continuous growth of network traffic, optical wireless communication (OWC) technology based on orbital angular momentum (OAM) can meet the needs of large-capacity modern communication and is ...
