Abstract
In this paper, the ADI-FDTD algorithm is applied to simulate scattering of three-dimensional objects. A few key techniques include the introduction of an incident plane wave, connective boundary condition between total-field zone and scattering-field zone and near-to-far field transformation are discussed. It is shown from the numerical result that the computation time of the ADI-FDTD algorithm is only 1/6 that of the conventional FDTD method with the same accuracy.
