Abstract
The frequency characteristics of the transverse magnetic (TM) surface waves at mid-infrared frequencies in a layered system, consisting of YBa2Cu3O7−x superconductor film bounded by a nonlinear antiferromagnet (FeF2) cover and a resonant semiconductor plasma (In0.53Ga0.47As) substrate, are fully described. The permeability tensor of the antiferromagnet crystal, for the absence of an applied Zeeman field, has a nonlinear response to the intense rf field. The complex wave number of TM wave is computed by solving the dispersion equation in order to determine the effects of the superconductor and resonant semiconductor on the dispersion characteristics for both the reduced phase and reduced attenuation constants as a function of the temperature and frequency. The power flow through the waveguide structure has also been investigated. We have found that superconductors have the ability to reduce the propagation losses. We have also found that the reduced attenuation constant is highly dependent on the temperature of the superconductor.
