Guided waves in a left-handed material guiding film with a ferrite cladding

Abstract

In this paper, a symmetric three-layer slab waveguide is investigated. The guiding layer and the surrounding medium are assumed to be left-handed materials of negative permittivity and permeability. The dispersion equations are derived for both TE and TM polarizations. The properties of the waveguide structure are investigated for different mode orders and for different parameters of the left-handed materials. The field profiles of the guided modes are presented in order to understand these properties.
