摘要
Abstract
In the conventional finite-difference time-domain (FDTD)method,fine cells reduce the time-step size due to the Courant-Friedrich-Levy(CFL)stability condition,which results in an increase in computational effort,such as the central processing unit (CPU)time.In the alternating-direction implicit finite-difference time-domain(ADI-FDTD)method,a larger time-step size than allowed by the CFL stabili-ty condition limitation can be set because the algorithm of this method is unconditionally stable.Conse-quently,an increase in computational efforts caused by fine cells can be prevented.The simulation experi-ments data by the ADI-FDTD method were compared with that by the conventional FDTD method.The results show that simulation field by ADI-FDTD method agree quite well with that by the FDTD method, but the required CPU time can be much shorter than that for the FDTD method.关键词
