Optimization of Wireless Power Transfer with Multiple Transmitters and Receivers Hans-Dieter Lang Doctor of Philosophy The Edward S. Rogers Sr. [] Key Method The methods are based on convex optimization, which effectively guarantees to find global maxima. Furthermore, implementations of maximally efficient systems are presented and investigated, to gain insight into how these limits may be achieved. Practical examples and related applications, including antenna arrays and magnetically mediated hyperthermia…
