Abstract:
A new definition of shielding effectiveness (SE) for enclosures with apertures and conducting objects is reported herein in which the SE parameter is calculated for the whole enclosure space. The conducting objects can vary from high frequency printed circuit boards (PCBs) to simple metal plates used as partitions. In this paper, the SE parameter is considered as a three dimensional (3-D) parameter which improves the understanding of the whole SE phenomenon. In addition, an enclosure loaded with a microstrip transmission line (MTL) is studied to illustrate the effect of perforated metallic shields on electromagnetic interference (EMI) generated by PCBs
