The Analysis of Propagation on Periodically Slotted Coaxial Cable above Lossy Ground.

摘要

After formulation of an integral equation and of the dispersion relation for a periodically slotted coaxial cable above and parallel to the air-lossy ground planar interface,the report addresses the evaluation of the exterior dyadic Green's function in a unit cell. The latter constitutes the heretofore not available in the literature kernel of the integral equation. The problem is reduced to an evaluation of the field of electric and magnetic multipole phased line sources above a lossy ground. The analysis of the various relevant integrals is carried out either in terms of an asymptotic expansion or rigorously by function theoretical methods. (Author)
