Negative refraction with magnetic resonance in a metallic double-ring metamaterial

Metallic metamaterials, by periodically arranged double rings, without splits in both of them, are investigated to show their negative refraction at the magnetically resonant transmission band. It is verified that the negative refraction occurs in the transmission regime where the electric response...

Description
Summary:Metallic metamaterials, by periodically arranged double rings, without splits in both of them, are investigated to show their negative refraction at the magnetically resonant transmission band. It is verified that the negative refraction occurs in the transmission regime where the electric response is attributed to the plasma oscillation of electrons, in analogy to the metallic cut-wire metamaterials, and the magnetic response is originated from antiparallel currents induced resonantly in the neighboring edges of the concentric double rings.
