Connection of vector and scalar potential fields in the three-dimensional analysis on the time domain

摘要

"Electromagnetic Interference (EMI)" has become serious problems as development of the digital technology, such as downsizing in devices and performing high-speed operation. In the EMI problem such as Electro-Static Discharge (ESO), not only the vector field from current sources but also the scalar field due to space charges are included. For these complicated problems, the numerical analysis on the three-dimensional space and the iterative computation on the time domain are effective. I have already proposed the adaptation of the vector potential to the time-dependent numerical method, especially, to the condensed node Spatial Network Method (SNM). In this paper, the fundamental property of the connecting both networks for the vector and the scalar fields by the equivalent current sources based on the gauge condition is investigated.
