Provided is a wave control medium capable of controlling waves while decreasing the size of a metamaterial or the like and increasing the bandwidth of the metamaterial or the like. A wave control medium 10 is formed by combining at least two among a coil 11 and a coil 12 which are three-dimensional microstructures formed into a spiral structure, the coil 11 and the coil 12 including any one of a metal, a dielectric material, a magnetic material, a semiconductor, and a superconductor, or a material selected from a plurality of combinations of these materials, and having functions of a capacitor and an inductor. The coil 11 and the coil 12 form a capacitor between the lateral face of the coil 11 and the lateral face of the coil 12 facing each other, and form an inductor by forming a three-dimensional multiple resonance structure by the coil 11 and the coil 12 having a spiral structure.
A wave control medium comprising at least two three-dimensional microstructures in combination, each of the three-dimensional microstructures including any one of a metal, a dielectric material, a magnetic material, a semiconductor, and a superconductor, or a material selected from a plurality of combinations of a metal, a dielectric material, a magnetic material, a semiconductor, and a superconductor, the wave control medium having functions of a capacitor and an inductor, wherein a distance of the wave control medium in a longitudinal direction is less than 1/10 of a wavelength of a wave, and a fractional bandwidth of a response is 30% or more.
A method for manufacturing a wave control medium, the method comprising forming a microstructure into a three-dimensional structure using a molecular template that uses self-assembly of an organic substance, the microstructure including any one of a metal, a dielectric material, a magnetic material, a semiconductor, and a superconductor, or a material selected from a plurality of combinations of a metal, a dielectric material, a magnetic material, a semiconductor, and a superconductor, wherein the wave control medium having functions of a capacitor and an inductor, and wherein a distance of the wave control medium in a longitudinal direction is less than 1/10 of a wavelength of a wave, and a fractional bandwidth of a response is 30% or more.
