Abstract

Metamaterial (MTM) slabs, realized using Split Ring Resonators (SRR’s) to enhance efficiency of Wireless Power Transfer (WPT) systems is discussed here. A detailed study of intrinsic properties obtained by simulation of the actual MTM slab is presented. An improvement in the wavelength to unit cell size of 813, at a low operating frequency of 5680 kHz is shown. Forward transmission coefficients (S₂₁) for with and without MTM slab cases are compared. In this low frequency regime, with simulated S-parameters an efficiency of ~ 68% is achieved by placing the MTM slab closer to receiver coil than the transmitter coil.
