Dyadic Green’s functions are powerful and efficient for solving the boundary problems in elec-tromagnetic theory.The key problem involved is how to deal with the additional term in the elec-tric dyadic Green’s function at the source region.In this paper,the dyadic Green’s functions forgeneralized 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,whoseintegral of continuous spectrum h has been eliminated,are given particularly.
