NONLINEAR TM SURFACE WAVES OF A THREE ANTIFERROMAGNET – SUPERCONDUCTOR STRUCTURE

Abstract

The characteristics features of TM nonlinear surface waves at infrared frequencies in a layered structure of an antiferromagnet, superconductor and linear dielectric have been performed. The complex wave number of TM surface wave is computed by solving the dispersion equation in order to find out the reduced phase and reduced attenuation index. The effects of the operating angular frequency and temperature of superconductor on the reduced phase and attenuation index have been examined. The power flow has also been studied as a function of the reduced phase and attenuation index for different values of the temperature of superconductor.
