| Abstract(in English) | The electrostatic discharge (ESD) due to charged metal objects produces the electromagnetic fields having broad-band frequency spectra over the microwave region, which cause serious electromagnetic interference to high-tech information equipment. From this perspective, in order to analyze the ESD fields caused by charged metal spheres, we previously proposed FDTD methods based on gap excitation with a spark current and spark voltage both derived from the Rompe-Weizel formula. For metals with asymmetrical shapes, however, the spark current and voltage cannot be obtained in closed forms so that the proposed method is not applicable to this case anymore. In this study, a new FDTD algorithm based on gap excitation with the time-variant conductivity and electric field of a spark channel has been proposed, which enables one to predict the ESD fields due to charged metals having arbitrary shapes. The algorithm has also been validated by a spark experiment. |
