Wave control medium, wave control element, wave control member, and wave control device

Abstract

To provide a wave control medium capable of absorbing and controlling waves while miniaturizing a metamaterial or the like and also increasing the bandwidth thereof. The present disclosure provides a wave control medium that includes a three-dimensional microstructure body including a base part, a metamaterial part, and a matching element disposed between the base part and the metamaterial part. The three-dimensional microstructure body is formed of a material selected from any one of a metal, a dielectric, a magnetic body, a conductor, a metal oxide, a semiconductor, and a superconductor, or a combination of a plurality of those above. The metamaterial part may have a helical structure, a multilayer structure, a conical structure, a wire structure, a ring structure, a mushroom structure, or a sphere structure.
