Kurzbeschreibung (Abstract)
Recently, the simulation of high frequency devices has become of increasing importance due to the demand for faster development processes. The Finite Difference Time Domain (FDTD) method has been proved to be an efficient tool for the simulation of electromagnetic phenomena. In the paper we derive a new consistent three-dimensional subgridding scheme for the Finite Integration Technique. In the time domain the latter method reduces to FDTD when only cubical cells are used. The subgridding extension can help to achieve accurate models of small structure details without heavily decreasing numerical efficiency while the properties of continuous Maxwell equations are still conserved in the grid space. After studying numerical dispersion and stability, the applicability of the method is demonstrated by regarding an example studying scattering at a small post in a rectangular waveguide.
