Several approaches to improve the numerical efficiency of the spectral-to-spatial domain transformation of the single-layered cylindrical mixed-potential Green's function are presented. Additionally, a method to compute the radiated far-field due to a previously determined equivalent surface current distribution on the substrate/air interface is presented as well. The numerical efficiency depends in both cases on the number of calls to spectral domain Green's function routines.
