Spectral domain dyadic Green's function for multilayer cylindrical structures

Cylindrical microstrip structures generally consist of several dielectric layers with distributed metallizations in arbitrary interfaces. A generalized method is developed to derive the dyadic Green's function for cylindrically stratified dielectric layers in spectral domain. The result is a clear equivalent circuit of the whole structure which is simple to apply and to evaluate. This is demonstrated in the application to some well-known simple configurations as well as structures with multiple metallizations in the interfaces.
