Paper 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 Ho = O and nonreciprocal for HoO. 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.
