The complete spectrum of image line

A derivation is presented of the complete orthonormalized spectrum, under LSA/LSM (longitudinal-section electric/magnetic) assumptions, for image line waveguiding structures by using a so-called method of partial wave phase shifts. The analysis is developed for the even LSM (TM/sup y/) polarization, having H/sub y/=0 and E/sub y/ as the main electric field component: the LSE analysis proceeds along dual lines. An arbitrary radiation field is described as a superposition of the LSM and LSE continua.<
