Abstract
A novel full-wave method aimed at analyzing axisymmetric waveguide devices is introduced in this paper. The method is based on the application of the equivalence theorem in order to decouple the outer and inner electromagnetic problems. The former refers to the access waveguides, the latter to the complex shape structure inside the device, which is modeled as a boundary value problem and solved by means of a multi-domain spectral method. Detailed comparisons with other simulation codes are reported for two benchmark structures and for a complex axisymmetric waveguide component.
