Negative-index Polarization-independent Metamaterial

Abstract

We introduce a polarization-independent left-handed metamaterial, and describe its electromagnetic properties using numerical techniques. Conventional mirrored S-shaped resonators are shown to exhibit a negative refractive index; and in this work a crossed design based on these resonators is demonstrated as a polarization insensitive metamaterial with negative effective index.
