A circuit approach to model composite structures affected by electrostatic discharge

This paper presents a circuit network analogue for the solution of the Maxwell's equations in composite structures affected by electrostatic discharge events. The proposed equivalent circuit cell consists of conductances, inductances and capacitances. A SPICE simulator is used to solve the resulting network in terms of voltages, currents and their corresponding field variables. The validity of the proposed approach is demonstrated by comparing the results obtained by means of the circuit solution and those computed by a dedicated finite difference code.
