Computation of Dyadic Green’s functions for generalized cylinders in free space

Abstract

Dyadic Green’s functions are powerful and efficient for solving the boundary problems in electromagnetic theory. The key problem involved is how to deal with the additional term in the electric dyadic Green’s function at the source region. In this paper, the dyadic Green’s functions for generalized cylinders in free space are derived with the technique in another paper of author (1984). The dyadic Green’s functions for conducting wedges, half-plates and elliptic cylinders, whose integral of continuous spectrumh has been eliminated, are given particularly.
