Negative refraction from quasi-planar chiral inclusions

Abstract

This letter proposes a quasi-planar chiral resonator suitable for the design of negative refractive index matamaterial. It is presented an analytical model for the determination of its polarizabilities, and the viability of negative refraction in chiral and racemic arrangements with the proposed inclusions is analyzed. The present analysis is expected to pave the way to the design of negative refractive index matamaterials made of a single kind of inclusions feasible from standard photo-etching techniques.
