Abstract
A new method is presented that allows the analysis of a combination of both circularly and rectangularly shaped subdomains in the same struc ture, The method is based on the use of polygonal grids in connection with the finite-difference method in the frequency domain, The converg ence behavior of this new efficient algorithm is analyzed and compared to conventional stair-case approximations for a circular waveguide. F inally, the dispersion characteristic of a square waveguide with a cir cular dielectric rod is presented.
