Magnetostatic surface waves on left-handed materials (LHM)

Abstract

The nonlinear characteristics of magnetostatic surface waves at microwave frequencies in a layered structure of left-handed material film and a semi-infinite linear ferrite substrate have been investigated. The general dispersion relation is derived and analyzed numerically. It is found that it has two solutions for ω (k), one represents a physical solution and other unacceptable. The effects of the applied external magnetic field around the proposed region have also been examined.
