Abstract

The coupling through apertures between an electrostatic discharge (ESD) current flowing on the external shield of a metallic enclosure and the electromagnetic field of its internal region is analyzed; the excitation of the electric field on the apertures by the ESD and then the evaluation of the internal field are calculated separately, by means of the finite difference time domain (FDTD) technique and the modal expansion, respectively. All the numerical results obtained with this simple and numerically efficient approach have been validated by measurements
