FDTD on nonorthogonal grids with triangular fillings

In this paper we present the combination of the FDTD method on nonorthogonal grids with the concept of triangular fillings. The resulting algorithm allows a more general mesh generation, where degenerated cells can usually be easily avoided, without additional computational cost or loss of modeling accuracy.
