Summary:
Due to unconditional stability of ADI-FDTD, it is becoming popular. In this paper progress of the ADI-FDTD method is given. First of all to get the advantages of both ADI-FDTD and FDTD methods a hybrid method is briefly explained. Then to reduce the error of the ADI-FDTD method at larger time steps error reduced ADI-FDTD is presented. To control the dispersion of the conventional ADI-FDTD method at higher time steps dispersion optimized ADI-FDTD method with different combinations for optimization is given.
