Low Loss Metamaterials Based on Classical Electromagnetically Induced Transparency

TL;DR

This paper presents a theoretical demonstration of achieving electromagnetically induced transparency in metamaterials using resonant mesoscopic oscillators, leading to low-loss, transparent electromagnetic responses.

Contribution

It introduces novel metamaterial designs that support dark resonant states and provides detailed analysis of their frequency-dependent electromagnetic properties.

Findings

Transparency window with low absorption and strong dispersion

Effective permeability and permittivity are frequency-dependent

Simulations confirm the low-loss transparency effect

Abstract

We demonstrate theoretically that electromagnetically induced transparency can be achieved in metamaterials, in which electromagnetic radiation is interacting resonantly with mesoscopic oscillators rather than with atoms. We describe novel metamaterial designs that can support full dark resonant state upon interaction with an electromagnetic beam and we present results of its frequency-dependent effective permeability and permittivity. These results, showing a transparency window with extremely low absorption and strong dispersion, are confirmed by accurate simulations of the electromagnetic field propagation in the metamaterial.
