Abstract
This paper presents a method to derive the Dyadic Green’s Function (DGF) of a loaded rectangular waveguide by using the image method. In the calculation of the DGF, we use the integral transformation and replace the multi-infinite summation by a single one; thus it greatly simplifies the calculation and saves computer time. As an example of the DGF’s application, we give the moment method’s scattering field calculation of a metal sphere resting on the broad wall of the loaded rectangular waveguide. Results of our calculations well agree with both data of experiments performed in our laboratory and those are published. It is easy to see that the method used in this paper can be expanded to other related waveguide problems.
