A General Simulation Framework for Radiative Wireless Power Transfer Systems Based On Phased-Array Transmitters
Paper in proceeding, 2023

Radiative wireless power transfer (WPT) is an emerging technology for charging moving objects (e.g., vehicles) or static user terminals (e.g., mobile handsets). The most popular radiative WPT techniques employ transmitter (TX) and receiver (RX) phased arrays with dynamic beamforming functionalities. In this paper, we present a simulation approach capable of accurately estimating main WPT characteristics such as received power and power transfer efficiency. The method employs the equivalence principle to approximate TX and RX antenna apertures during the charging process, whereas antenna coupling is computed using the reaction concept. We demonstrate several multi-RX charging examples for different amplitude-only TX autofocusing algorithms. The discussion is complemented by an RX rectifier performance consideration.
