Abstract
Metamaterial is an artificial material with unique material properties that cannot be found in a naturally existing one, and hence it is able to perform functions that a conventional material cannot do. Consequently, it has shown great potential in various engineering applications such as resonance coupled mid-range wireless power transmission (R-WPT) systems. However, the analysis and design of an application-oriented metamaterial include both the unit cells and their combinations, and thus are very complex. Moreover, the performance of a metamaterial is very sensitive to uncertainties in both manufacturing and operating conditions. In this regard, a two-phase methodology for robust design optimizations of metamaterial slabs in R-WPT applications is proposed and applied to the design optimization of a prototype R-WPT system with promising results.
