FIELD PENETRATION INTO METALLIC ENCLOSURES THROUGH SLOTS EXCITED BY ESD

In this paper the coupling through apertures between an ESD current fl owing on the external shield of a metallic enclosure and the electroma gnetic 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 FDTD te chnique and the modal expansion, respectively. All the numerical resul ts obtained with this simple and numerically efficient approach have b een validated by measurements.
