Abstract :
Polyhedral finite elements of lowest order are introduced in the formulation of the finite integration technique (FIT). The resulting availability of general polyhedral element shapes in the FIT facilitates e.g. consistent subgridding or consistent grids containing both hexahedral and tetrahedral elements without resorting to interpolations. To show the practical suitability of the scheme, the frequency response of a dielectric filter is calculated and compared to the results of a standard simulation tool.
