Investigation of hybrid metamaterial for enhancing efficiency of wireless power transfer systems [PDF]

2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2017
Applying metamaterial mechanism into the wireless power transfer (WPT) system is one of potential methods for improving power transfer efficiency (PTE). Different from the conventional metamaterial slab with single negative permeability (SNP), the WPT with hybrid negative permeability (HNP) slab has higher PTE.
