Abstract :
Waves with complex propagation constants occur in the modal spectrum of shielded rectangular dielectric image guides, although the guide is assumed to be lossless. Dispersion characteristics are presented, calculated by a rigorous mode-matching technique. Plots of power flow show that the energy supported by such a complex wave returns to the plane of excitation.
