Efficient finite-difference time-domain modeling of short-gap electrostatic discharge caused in the vicinity of a complex electronic system

This paper addresses efficient finite-difference time-domain (FDTD) modeling of transient interactions of complex electronic systems with electrostatic discharge occurred at a short air gap. A partially implicit FDTD scheme with the nonlinear spark resistance model by Rompe and Weizel is applied to a realistic personal computer model. Its efficiency and accuracy are assessed in comparison with Yee's FDTD method.
