Abstract
To provide a wave control medium that can absorb and control wave motion while achieving downsizing and wider bandwidth of a metamaterial and the like. A wave control mediumincludes a three-dimensional microstructure having a base, a spiral part, and a matching elementdisposed between the baseand the spiral part, in which the three-dimensional microstructure includes a material selected from any one of a metal, a dielectric, a magnetic body, a semiconductor, and a superconductor, or a combination of a plurality of these materials. The wave control mediumcan absorb the wave motion by having the matching elementdisposed between the baseand the spiral partto moderate a change in the entire impedance value.
