Vector wave function expansion for dyadic Green's functions for cylindrical chirowaveguides: An alternative representation

In this paper, a vector wave function expansion of dyadic Green's functions is made to characterize electromagnetic waves in lossless, reciprocal and homogeneous chirowaveguides. Using orthogonalities among these vector wave functions, the Ohm-Rayleigh expansion, and the method of (G) over bar(m), a re represent the Green's dyadic in terms of the modified Vector wave functi ons. It is realized that the conventional procedure of the vector wave expa nsion described in the normal texts cannot be directly applied to the formu lation of the Green's dyadic in chirowaveguides. Some generalized orthogona lities among these vector wave functions in the chirowaveguides have to be considered when deriving the dyadic Green's functions.
