Patent ID: RE41594

Claim:
A frameless vent panel adapted to shield against electromagnetic interference (EMI) comprising: a dielectric panel having a thickness defined by a first side and a second side, and defining a plurality of apertures, said dielectric panel further having a perimeter; a first electrically conductive layer applied to the dielectric pane panel , wherein the conductively coated dielectric panel attenuates a transfer of electromagnetic energy from the first side to the second side of the substrate ; and a strip of compressible conductive foam material, said strip having a width substantially equal to the thickness of said dielectric panel and being wrapped around the outer perimeter thereof and substantially covering said thickness between said first side and said second side , whereby the frameless vent panel is configured to be mounted within an opening in a manner such that the strip of compressible conductive foam material around the outer perimeter of the dielectric panel is compressed .
