Abstract :
In this paper, the very accurate and efficient modal analysis of arbitrarily shaped waveguides, whose cross-section is defined by a combination of straight, circular and/or elliptical arcs, is solved. An extension of the well-known boundary integral-resonant mode expansion (BI-RME) method is proposed. Successful comparisons with available numerical and experimental data fully demonstrates the validity of the improved BI-RME method proposed.
