Non-linear surface waves at a single interface of semimagnetic semiconductor–left handed materials (LHM)

Abstract

The nonlinear characteristics of TE surface waves at microwave frequencies in a layered structure of non-linear semimagneticsemiconductor cover and left-handed material substrate have been investigated. Numerical analysis and derivation were carried out for the dispersion relation in its general form. The power flow has also been studied as a function of wave number for different frequencies and magnetic fields. It is shown that the proposed waveguide structure depends significantly on the operating wave frequency and can be efficiently controlled by varying the frequency.
