| Research Abstract |
Aiming at the next generation EMC and highly functional antenna, the left-handed metamaterials having the negative permeability (MNG) and permittivity (ENG) in the microwave range have been investigated, and the application research for the electromagnetic wave absorber, shielding materials and the low frequency matching of microwave antennas have been conducted. The granular composites having the MNG and the ENG property were developed. For the EMC applications, a thin wideband electromagnetic wave absorber and frequency selective shielding sheets have been developed. Further, we have demonstrated that the matching frequency of a patch antenna can be reduced by the space matching effect of the MNG property of magnetic metamaterials.
