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 influence of boundary-conditions on resonant frquencies of cavities in 3-D FDTD algorithm using nonorthogonal coordinates. [PDF]
The 3-dimensional finite-difference time-domain method in non-orthogonal co-ordinates (non-standard FDTD) is used to calculate the frequencies of resonators. The numerical boundary conditions of the method are presented.
