Resonant features of planar Faraday metamaterial with high structural symmetry

TL;DR

This paper investigates the resonant behavior of a highly symmetric planar Faraday metamaterial, analyzing its electromagnetic transmission, polarization rotation, and resonance characteristics both theoretically and experimentally.

Contribution

It introduces a novel planar Faraday metamaterial with high symmetry and characterizes its resonant and polarization rotation properties through combined theoretical and experimental methods.

Findings

Resonance frequency depends on the structure and magnetic field.

The metamaterial exhibits significantly higher polarization rotation than a single ferrite slab.

The frequency and magnetic field ranges for enhanced rotation are identified.

Abstract

The transmission of electromagnetic wave through the planar chiral structure, loaded with the gyrotropic medium on the longitudinal magnetic field is studied. The frequency dependence of the metamaterial resonance and the angle of rotation of the polarization plane are obtained. We define both theoretically and experimentally the range of frequencies and magnetic fields, where the angle of polarization plane rotation for the metamaterial is essentially higher than for a single ferrite slab.
