An electromagnetic interference (EMI) shield that increases the airflow through the EMI shield while preventing line-of-sight openings through the EMI shield. Two plates are coupled together. Each of the respective plates has a raised component with an aperture therethrough to provide a path through the plate. The raised component is preferably scoop-shaped with the aperture at one end and an opposite end tapering into the respective plate. At least a portion of one of the raised components overlaps at least a portion of the other of the raised components when the plates are coupled together to form a path through the plates, while the plates are coupled together. Line-of-sight openings through the plates, to an electronic device protected by the EMI shield, are at least partially prevented by the raised components.
