Calculation and Measurement of Transient Fields from Voluminous Objects


Numerical methods for the calculation of transient fields from ESD have been published recently. The methods simplify the problem either by neglecting the arc or just calculating simple geometries. A complete solution would require the calculation of a lossy 3D nonlinear problem with numerically hard to handle dimension. Nevertheless, due to the nonlinearity of the arc, time domain methods are preferable. In this paper, numerical calculations of transient field from ESD have been studied. The influence of this approach on the static charge distribution and voltage is discussed. Results of a thin wire Method of Moments calculation are also presented, and the numerical method for the calculation of voluminous objects outlined.
