Abstract :
In this paper, two new hybrid FDTD algorithms, formulated via the cell method (CM), are presented for the analysis of structures with fine details. The level of reflection introduced by the interface of dissimilar mesh (subgridding or triangular mesh) in two different regions of the computational domain is studied, and the results are presented for different approaches for the sake of comparison. The paper also shows that the accuracy of the field computation can be significantly improved by using a fine triangular mesh and the CM/new FDTD algorithm in which the time step used is the same in the two domains.
