摘要：

We present a frequency domain finite difference approach in curvilinear coordinates to the computation of the modes of circular ridged waveguides. The use of a polar mesh allows to avoid staircase approximations of the boundary, providing a very effective and accurate procedure. The proposed approach has been assessed, both in terms of accuracy and effectiveness, against general-purpose software, namely CST Microwave Studio and Ansys BTSS, showing a significant reduction of the computational burden.
