Investigation of the propagation characteristics of magnetostatic surface waves in a layered structure of left-handed materials (LHM) and ferrite (YIG)

Abstract

The characteristics of magnetostatic surface waves at microwave frequencies in a layered structure of left-handed material film and a semiinfinite 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.
