Novel Wireless-Power-Transmission (WPT) Model Based on a Bi-Characteristic-Impedance Transmission Line (BCITL)

The wireless power transmission (WPT) technology has widely applied in our modern society. For general WPT scenarios with multipath propagation, the WPT equation based on two-port network parameters associated transmitting and receiving antennas provides accurate and flexible solutions. However, it does not provide a physical insight of WPT mechanisms for a specific WPT scenario. In this paper, a novel WPT model based on a bi-characteristic-impedance transmission line (BCITL) is proposed to provide accurate results with an equivalent physical connection between transmitting and receiving antennas, resulting in better physical insight of WPT mechanisms. In addition, numerical results will be provided to validate the accuracy and effectiveness of the new WPT model.
