摘要
The propagation characteristics of nonlinear TE surface waves at a lateral antiferromagnetic/nonmagnetic superlattices (LANS) substrate and a nonlinear magnetic cover have been investigated. LANS which are linear frequency-dependent gyromagnetic media, are described with an effective medium theory. It is found that the dispersion of the TE waves show the optical bistability behavior. The optical bistability is affected by the magnetic fraction f(1). We also calculate and illustrate the variation of the wave index with the power flow for various values of f(1). We found that the decrease in f(1) makes the power threshold of nonlinear TE surface waves decrease.
