摘要

We present a rigorous optimization method to design wireless power transmission (WPT) systems. In order to optimize the power coupled to the receiver, reactive parasitic components are integrated into the system. Simulated annealing is implemented in conjunction with the method of moments to determine the optimum parameters for the design. By carefully adjusting the geometry, size, position and properties of the parasitic wires, it could be seen that the peak efficiency and effective distance for power coupling could be significantly improved. The result shows that the implementation of a square parasitic wire gives better performance than a circular one. A WPT system with a square reactive wire gives respectively a 0.79% and 0.07. improvement in peak efficiency and effective distance compared to its zero-impedance counterpart. By inserting two square reactive wires with the transmitter sandwiched in between, the peak efficiency and effective distance are found to have increased respectively by 3.37% and 0.18., compared to that with a single reactive wire.
