Abstract

In this paper, updating schemes for the alternating-direction implicit finite-difference time-domain method(ADI-FDTD) are studied, which method has the potential to considerably reduce the number of time iterations especially in case where the fine spatial lattice relative to the wavelength is used to resolve fine geometrical features. In numerical simulations for microwave structure using ADI-FDTD, time marching scheme comprises of two sub-iterations. Two different updating equation sets for ADI-FDTD simulations are presented. In order to discuss the characteristics of those schemes especially in view of applying boundary conditions, we solved two complementary 2-D problems.

본 논문에서는 관심 주파수의 파장에 비하여 매우 섬세한 구조의 해석에 있어서 기존의 FDTD보다 효율적인 해석이 가능한 ADI-FDTD의 차분방정식 계산 방법에 대하여 연구하였다. 반복 구간에서 계산되는 서로 다른 계산 방법을 유도하고 두 개의 상보적인 2차원 문제를 해석하여 경계 조건의 적용 관점에서 그 특성을 논하였다.
