A three-dimensional isotropic metamaterial, comprising an aggregate of meta-atom block pieces in which meta-atoms are buried in a transparent resin, in a transparent resin member.
A method of producing a three-dimensional isotropic metamaterial, comprising the steps of:
- a step (P1) of forming a conductive member film on a transparent resin film (1a) and etching the conductive member film to form a meta-atom block aggregate;
- a step (p2) of bonding transparent resin films (1b) after coating the meta-atom block aggregate with transparent resin solution;
- a step (p3) of splicing the transparent resin film (1a) to a substrate sheet (2) after drying;
- a step (p4) of dicing the meta-atom block aggregate into a predetermined size, and then removing the diced aggregate from the substrate sheet (2) as a block piece in which a meta-atom is buried in a transparent resin (1);
- and
- a step (p5) of uniformly dispersing the meta-atom buried block pieces in transparent resin solution in a mold and then causing curing, and extracting a cured molded member from the mold.
