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 ...

A dual-mode (l=-1 and 3) orbital angular momentum (OAM) antenna array is described in this paper. Gene Algorithm (GA) method is used to optimize the excitation of antenna array for separating ...

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