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 medium 5 includes a three-dimensional microstructure having a base 2, a spiral part 3, and a matching element 6 disposed between the base 2 and the spiral part 3, 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 medium 5 can absorb the wave motion by having the matching element 6 disposed between the base 2 and the spiral part 3 to moderate a change in the entire impedance value.
A wave control medium comprising a three-dimensional microstructure having a base, a spiral part, and a matching element disposed between the base and the spiral part, wherein
A manufacturing method of a wave control medium, the manufacturing method comprising forming a microstructure into a three-dimensional structure using a molecular template that utilizes self-assembly of an organic substance, the microstructure including 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 the metal, the dielectric, the magnetic body, the semiconductor, and the superconductor, wherein the three-dimensional microstructure having a base, a spiral part, and a matching element disposed between the base and the spiral part.
