Abstract
A metamaterial for an electromagnetic wave filter includes a substrate; and a film disposed on the substrate and having a set of slots arranged to form a rotationally symmetric pattern, which is patterned in an intaglio shape, or a set of structures arranged to form a rotationally symmetric pattern, which is patterned in an embossed shape, to control a transmission rate according to polarization of an electromagnetic wave incident on the film. The set of slots or the set of structures have an array angle that is determined such that the transmission rate and a reflectivity thereof have constant values according to the polarization of the electromagnetic wave incident on the film, and have a chloroplast molecular structure pattern in which the set of slots or the set of structures are arranged in pentagonal and hexagonal shapes.
