Paper Abstract

Electromagnetic emissions from electronics associated with explosives is a potential detection modality, both passive listening, and stimulated RF emissions. However, the parasitic paths by which energy is coupled off a printed circuit board from an active device, and by which external energy can be coupled onto the board and to a device, must be identified and characterized. One such noise-coupling path is identified in this work, and a modeling approach demonstrated. In particular, coupling of noise from the DC power bus of a multilayer printed circuit board that uses entire metal layers for power and ground, and an I/O line that transitions through the DC power planes is investigated.
