- Abstract
- In this paper, we investigate the role of current loop in the generation of second and third harmonic signals from magnetic metamaterials and we are clarifying why two polarized harmonics are generated from magnetic metamaterials. We show that the current loop formed in the magnetic resonant frequency acts as a source for nonlinear effects. The current loop that has a circular shape can be divided into two orthogonal parts, where each of these parts acts as a source for generating a harmonic signal parallel to itself. The type of harmonic signal is determined by the metamaterial's inversion symmetry in that direction. This claim is also supported by the experimental results of another group. (C) 2017 Elsevier B.V.
