Abstract
A gasket assembly for sealing electromagnetic waves includes a canted-coil spring for blocking the propagation of electromagnetic waves therepast. The canted-coil spring includes a plurality of individual coils canted along a centerline thereof. A groove is provided for supporting the coil spring in a position enabling loading of the coil spring along a selected direction. The groove is provided with a selected surface for causing individual coils to always turn in a selected angular direction in order to control electromagnetic shielding effectiveness of the coil spring.
