Abstract

Recently, the Finite-Difference Time-Domain (FDTD) method is widely used for solving electromagnetic wave problems such as the scattering, diffraction, propagation, coupling etc. As the FDTD method is an explicit type finite difference method, it must be solved under Courant-Friedrich-Lewy (CFL) condition. Therefore, it is assumed that the calculation time increases when an analysis domain is very large or a cell size is very smaller than the wavelength of the electromagnetic wave. In this paper, the validity and usefulness of the Alternative Direction Implicit FDTD (ADI-FDTD) method, which is removed the constraints of CFL condition, are confirmed numerically when ADI-FDTD method is applied to the propagation and the scattering by a cylinder.
