Abstract :
The unconditionally stable alternating-direction-implicit (ADI)-FDTD method for bodies of revolution (BOR) is extended to Debye dispersive media based on the auxiliary differential equation (ADE) formulation. To validate the proposed algorithm, two numerical examples are given. Compared with the 3-D FDTD result, they show good agreement and at least 83% of memory and 55% of running time is saved for CFLN=2.
