Abstract

Abstract

The voltage response of a printed circuit board (PCB) in a metallic shielding enclosure excited by an external electromagnetic field is an important factor when considering the coupling of an external electromagnetic field to electronic systems. In this paper, the voltage response of PCB excited by an external source is calculated under two conditions: in free space and in the shielding enclosure. The frequency spectrum of voltage is calculated. When the PCB is put into the cavity with a long slot, some cases are considered including different electric field directions of incident source and different slot shapes. The variance of coupling coefficient is also calculated．
