Abstract

The eigenfunction expansions of the second electric dyadic Green´s function for a half infinite coaxial waveguide can be derived based on the method of Gm, whereby the irrotational vector wave function L is not needed. This work presents detailed derivation, in which scattering superposition and boundary condition on dyadic tangential magnetic field are used. The result can be directly used to analyze EMI caused by slot and aperture coupling.
