Abstract

In this paper, the propagation characteristics of nonlinear surface waves at a lateral antiferromagnetic/nonmagnetic superlattices (LANS) substrate and a nonlinear dielectric cover have been investigated. LANS super-lattices (antiferromagnetic-non magnetic) which are linear frequency-dependent gyromagnetic media, described with an effective-medium theory. We found that the nonlinear magnetic waves are reciprocal for H_o = O and nonreciprocal for H_o ≠ O. We also calculate and illustrate the variation of the wave index with the power flow for various values of the magnetic fraction f₁. We found that the nonlinearity interface is a very frequency dependent.
