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.Keywords
