description

In this paper we propose to use the Surface Integral Equation technique for the analysis of arbitrarily shaped Hplane obstacles in rectangular waveguides, which can contain both metallic and/or dielectric objects. The Green functions are formulated using both spectral and spatial images series, whose convergence behavior has been improved through several acceleration techniques. Proceeding in this way, the convergence of the series is not attached to the employment of any particular basis or test function, thus consequently increasing the flexibility of the implemented technique. In order to test the accuracy and numerical efficiency of the proposed method, results for practical microwave circuits have been successfully compared with other numerical approaches. The authors would like to thank Alcatel Alenia Space (Madrid, Spain) for having provided data of the lossy dielectric loaded evanescent waveguide filter. They also wish to acknowledge the economic support of MEC, Spanish Government, through the coordinated Research Project TEC2004/04313-C02.
