Abstract
In this paper, a generalized scheme for nonorthogonal grids is introduced to the ADI-FDTD method. To reduce the complexity, the localized nonorthogonal grids are applied to anomalistic regions only, and standard FDTD grids are used for other computational regions. The conversion from the nonorthogonal grid to the Cartesian grid is done by using the Jacobi transform. It should be mentioned that in the new scheme, the second-order Mur's absorbing boundary condition (ABC) can be used with the standard FDTD, which greatly simplifies the problem
