Optimal Aperture Distribution for Maximum Power Transfer in Planar Lossy Multilayered Matters
Paper i proceeding, 2015

We combine array-signal-processing and spectral domain techniques to determine the optimal aperture current distribution that maximizes the power coupling between two antenna apertures which are located on opposing sides of a multilayered lossy structure in the near-field. The resulting optimal distribution can be used as a reference in the design of antennas for near-field applications, such as for the detection of foreign objects in lossy media, wireless charging of implant batteries, or near-field communications with an implant. A MoM approach is formulated to study the performance of the optimal aperture currents in a simulated detection application in the presence of a small PEC patch, and it is shown that the optimal aperture current can improve the system sensitivity and increase the detection probability of the object.
