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.

针对下一代电磁兼容和高功能天线，研究了微波范围内具有负磁导率（MNG）和介电常数（ENG）的左手超材料，并进行了电磁波吸收材料、屏蔽材料和微波天线低频匹配的应用研究。研制了具有MNG和ENG性能的粒状复合材料。针对电磁兼容应用，研制了宽频带薄型电磁波吸收器和频率选择屏蔽片。此外，我们还证明了磁性超材料的MNG特性的空间匹配效应可以降低贴片天线的匹配频率。
