Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A metamaterial for an electromagnetic wave filter, the metamaterial comprising: 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, wherein 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 wherein the set of slots or the set of structures have a chloroplast molecular structure pattern in which the set of slots or the set of structures are arranged in pentagonal and hexagonal shapes. 2. The metamaterial of claim 1 , wherein the set of slots or the set of structures have a honeycomb structure pattern in which the set of slots or the set of structures are arranged at 0°, 120°, and 240° with respect to a vertical direction. 3. The metamaterial of claim 1 , wherein the substrate comprises quartz, silicon, sapphire, or glass. 4. The metamaterial of claim 1 , wherein the film comprises gold, silver, copper, or aluminum.
