Abstract
Recently increasing works have been devoted to study and fabricate new artificial materials called
metamaterials or left handed materials. These materials have unusual behavior as they have
simultaneously both negative permittivity and permeability.
In this paper, we investigate the effect of left handed materials and the conductivity of semiconductor
material on the dispersion characteristics of left-handed-ferrite-semiconductor waveguide structure, and
then we discuss the stability of magnetostatic surface waves in the mentioned three waveguide structures by
perturbation method.
