Left-handed chiral isotropic metamaterials: analysis and detailed numerical study

Abstract

Chiral isotropic metamaterials with a negative index of refraction design consisting of arrays of a sole structure are proposed. The Cn point group is selected based on its chiral and isotropic properties. A circuit analysis model is obtained for the double negative NIR passband design. The structure's orientation provides flexibility to adjust the properties. Structure modification, based on the capacitance and inductance value, controls the locations of the structure's effective material parameters and the double negative NIR passband. These proposed designs give the highest possible rank of isotropy. The negative index of refraction is also validated.
