Abstract :
This paper presents the electromagnetic interference shielding impact due to air vent holes on electronic systems chassis. In the study, finite-difference time domain (FDTD) simulations are used to investigate effects of aperture hole size on shielding performance. A numerical analysis is then proposed which enables mathematical quantification of expected shielding as a function of holes number, size, depth and hole-to-hole separation distance.
