A bi-isotropic hexachiral grid in PCB

Abstract

A bi-isotropic chiral structure has been numerically studied. It is composed of two layers of planar, 2Dchiral, honeycomb-like, parallel grids. Electromagnetic activity (gyrotropy) is observed. That leads to a strong chiral behavior with low losses. Keywords-electromagnetic metamaterials; chiral structures I.

A Full-Dielectric Chiral Material Based on a Honeycomb Structure

“…It is worth of noticing that, among other alternatives, three-dimensional chirality may be achieved by means of planar structures, if several layers of the structure are used, through electromagnetic coupling between the different layers [20][21][22][23][24][25][26]. A bilayered, metallic, chiral honeycomb was studied in [27], and electromagnetic activity was found. In this work, we have performed an electromagnetic analysis of a full-dielectric chiral honeycomb made by two layers, the second one being the specular image of the first one (see Figure 1).…”
