The role of current loop in harmonic generation from magnetic metamaterials in two polarizations

TL;DR

This paper explores how current loops in magnetic metamaterials contribute to harmonic generation, revealing that their orthogonal components produce harmonic signals in two different polarizations.

Contribution

It demonstrates that current loops in magnetic resonances act as sources of nonlinear effects, leading to polarization-dependent harmonic signals, a novel insight into metamaterial nonlinearities.

Findings

Current loops generate second and third harmonic signals.

Harmonic signals are polarized orthogonally due to current loop components.

Magnetic resonance acts as a nonlinear source in metamaterials.

Abstract

In this paper, we investigate the role of the current loop in the generation of second and third harmonic signals from magnetic metamaterials. We will show that the fact that the current loop in the magnetic resonance acts as a source for nonlinear effects and it consists of two orthogonal parts, leads to the generation of two harmonic signals in two orthogonal polarizations.
