| Abstract(in English) | In recent years, it is necessary to evaluate electrostatic discharge (ESD) immunity using numerical simulation in a design process of electronic equipment, and to consider effective countermeasures in advance. For the ESD immunity analysis of actual products, the conventional finite-difference time-domain (FDTD) method has been commonly used. However, the maximum stable time step size allowed for the stability condition of the FDTD method has to be reduced in the analysis of problems with thin structures or a short air gap. In order to overcome this problem, the author has been working on the development of a new semi-implicit FDTD method with a relaxed stability condition and its extensions. In this work, we outline the developed semi-implicit FDTD method and its relevant techniques, and then show its effectiveness in the analysis of ESD events for a practical thin metallic chassis. |
