RECTANGULAR WAVE-GUIDES WITH 2 CONVENTIONAL AND 2 SUPERCONDUCTING WALLS

The propagation properties of TE(pm) modes and their dispersion relati ons in rectangular waveguides with two conventional and two supercondu cting walls, derived by using the Meissner boundary conditions on the superconducting walls, are presented. In addition to recovering some p reviously known results, some novel results have been obtained: the cu t-off wavelength of the dominant TE(10) mode is greater than that of t he conventional TE(10) mode, and the tangential electric field and nor mal magnetic field for the dominant mode TE(10) exist on the supercond ucting surfaces. Expressions for electromagnetic components, surface c urrents, attenuation coefficient, maximum transmitted power, dispersio n and wave impedance are also presented.
