Partially Implicit FDTD (PI-FDTD) Method for Lower Dispersion and Anisotropic Errors

A new partially implicit 3D FDTD (PI-FDTD) method is introduced. The method is not unconditionally stable, but its stability limit is 6 times higher than that of the classic Yee’s FDTD method. The method has only one implicit update equation and uses four split time steps. A study has bee...
