Abstract: In this paper, a planar double-layer PCB uniform circular array (UCA) system is designed to generate orbital angular momentum (OAM) beams. The UCA system consists of planar directional ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Abstract: A calibration method based on orbital angular momentum (OAM) is proposed for gain-phase errors in uniform circular array (UCA). The idea of the method is to construct an objective function ...
