TL;DR

This paper explores how arrays of left-handed cylinders create complex guided modes and Fano resonances that significantly affect electromagnetic wave propagation and absorption in photonic structures.

Contribution

It demonstrates the impact of negative permeability matching on guided modes and resonance phenomena in photonic crystals with left-handed components.

Findings

Resonances alter the band spectrum of the array.

Fano resonances increase wave absorption.

Guided modes are influenced by permeability matching.

Abstract

We show that the periodic array of left-handed cylinders possesses a rich spectrum of guided modes when the negative permeability of cylinders equals exactly to minus value of permeability of embedding media. These resonances strongly influences propagation of electromagnetic waves through photonic structures made from left-handed materials. A series of Fano resonances excited by incident wave destroys the band frequency spectrum of square array of left-handed cylinders and increases considerably the absorption of transmitted waves.
