Abstract :
By combing the FDTD and the FD2 method, a nearly ideal absorbing boundary together with a mode extraction algorithm for arbitrariy shaped homogeneously filled waveguides is realized. With this extension of the FDTD method multi-mode analysis of waveguide components can be done in an efficient and versatile manner. The simulations performed to verify the algorithms show excellent agreement with previously published data.
