Abstract :
A finite-element formulation for the modal analysis of chirowaveguides is described. It constitutes a generalisation of the vector EH formulation, which has earlier been found to be without spurious nonphysical solutions. The validity of the suggested formulation is confirmed by comparing obtained dispersion relations for a circular chirowaveguide with corresponding exact solutions, the correspondence was found to be excellent.
