Abstract :
Since it was developed, the compact 2D FDTD method and its variations has been applied to analysis of 3D guided-wave structures. It saves quite significantly on memory and computing time. However, it is mainly used for obtaining dispersion characteristics of guided-wave structures with non-TEM modes. It can not be employed to solve discontinuity problems that lie in the propagation direction. In this paper, a new compact 2D FDTD method is proposed for any guided-wave structures that are geometry uniform in one of the transverse directions. It can be used to compute both dispersion and discontinuity of the guided-wave structures. To the author´s best knowledge, the issue has not been addressed so far
