Abstract
A resilient electromagnetic shielding gasket utilizes a plurality of conductive wire coils which are loaded in a manner so that coil spacing may be selectively adjusted at specific areas along the circumference thereof in order to provide an electromagnetic shield. Other portions along the circumference of the gasket provide sufficient biasing capability to take up for variations that may occur due to torquing, eccentricities, irregularities and other variables and thereby imminent contact between mating surfaces under load. The spacing along a seal-load portion of the gasket is selected to limit the passage of electromagnetic energy with a wavelength greater than a selected value.
