Circuit network analog for ESD current strikes composite structures

This paper presents a circuit network analog for the solution of Maxwell's equations in composite structures affected by an electrostatic discharge event. The proposed equivalent circuit cell consists of conductances, inductances and capacitances. The 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 with those computed by a dedicated finite difference code.
