Evaluation of Efficiency and Isolation in Wireless Power Transmission Using Orbital Angular Momentum Modes

Abstract

In this study, we aim to realize SWIPT (Simultaneous Wireless Information and Power Transfer) at the same frequency using the OAM (Orbital Angular Momentum) mode. To investigate which OAM mode is desirable for WPT (Wireless Power Transmission) and how much isolation can be realized, we studied how the power transmission efficiency and the mode isolation was changed depending on the transmission distance in the simulation. We have revealed that the mode 0 is desirable for WPT and the high isolation can be realized using the OAM mode.
