Abstract

Simplified model of the human generated electromagnetic field during an ESD event V. Amoruso & F. Lattarulo Dipartimento di Elettrotecnica ed Elettronica, Politecnico di Bari, Italy Abstract A multiple-sphere electromagnetic model of an operator-victim system is here proposed. The model could substantially be assumed as the generalization of an electrostatic approach initially finalized to the calculation of partial capacitances. Such lumped parameters are inserted into an RLC network subject to capacitive discharge. Resolving the network for the currents allows the ESD total current to be reconstructed and, additionally, the complex man-victim charge transfer to be explicited. The partial currents specifically associated to the discharges of each pre-charged capacitance form the set of pre-assigned feeding currents required by a subsidiary field computation. The latter, which substantially represents the subject of the present paper, is given by exploiting an exact solution of Maxwell's equati
