We present a frequency domain finite difference approach in curvilinear coordinates to the computation of the modes of elliptical ridged waveguides. The use of a elliptical mesh allows to avoid staircase approximations of the boundary, providing a very effective and accurate procedure.

Abstract
We present a frequency domain finite difference approach in curvilinear coordinates to the computation of the modes of elliptical ridged waveguides. The use of a elliptical mesh allows to avoid staircase approximations of the boundary, providing a very effective and accurate procedure.
