A method of analysis of TE/sub 11/-to-HE/sub 11/ mode converters

Abstract

An efficient method for the determination of the scattering matrix of TE/sub 11/-to-HE/sub 11/ corrugated cylindrical waveguide mode converters has been developed, based on the representation of the fields inside the corrugations by a small number of radial waveguide modes. Numerical results show that the method, when compared to the usual mode-matching techniques, reduces the computation time without loss of accuracy.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
