Beamforming in the Generation of Range-Time-Dependent Orbital Angular Momentum Based on the Circular Frequency Diverse Array
In this article, we combine the frequency diverse array (FDA) with the vortex electromagnetic wave theory and propose a beamforming method in the generation of range-time-dependent orbital angular momentum (OAM) based on the circular FDA (CFDA). First, we establish a CFDA-based OAM-generating struct...
