Defect-Induced Resonant Tunneling of Electromagnetic Waves Through a Polariton Gap

TL;DR

This paper demonstrates that introducing a defect in a 1-D atomic chain with a polariton band gap enables resonant tunneling of electromagnetic waves at specific frequencies related to local polariton states.

Contribution

It provides an analytical demonstration of defect-induced resonant tunneling in a polariton band gap, highlighting the role of local polariton states.

Findings

Resonant transmission occurs at defect-associated local polariton frequencies.

Defects enable electromagnetic wave tunneling through the polariton gap.

Analytical model confirms the resonance mechanism.

Abstract

We consider tunneling of electromagnetic waves through a polariton band gap of a 1-D chain of atoms. We analytically demonstrate that a defect embedded in the structure gives rise to the resonance transmission at the frequency of a local polariton state associated with the defect.
