Computer simulation of electrostatic discharge (ESD) for simplified objects is described and compared to measured transient fields of human/metal ESD. The simulation algorithm uses the method of moments in time domain, coupled with nonlinear arc resistance model. Transient currents and fields are analyzed from the electromagnetic compatibility (EMC) point of view. Validation of the numerical simulation is done by comparison to experimental data. The simulated structure models the human/metal ESD in its peak current and field values and their derivatives reasonably well.

Currents, current derivatives and transient fields of ESDs of humans are compared to currents and fields caused by simulators. A method for the simulation of the discharge current is provided. This method includes an arc model. The resulting high peak current values (>IO NkV) are validated by a simple physical model of the hand geometry. Investigations of transient fields from simulators point at differences between simulators from different manufactures and between the transient fields caused by humans compared to the fields from simulators. Suggestions for possible improvements of the ESD test standard are given.
