1. Electromagnetic shielding spring gasket assembly comprising:

  • coil spring means for blocking the propagation of electromagnetic waves therepast, said coil spring means comprising;

    a plurality of coils having a major and a minor axis and canted along a center line defined by an intersection of the major and minor axes, said coils being interconnected in a manner forming a radial garter-type canted-coil spring;

    back angle means for both defining the disposition of a trailing portion of each coil with respect to a line normal to the center line and for determining a radial load-deflection characteristic of the canted-coil spring assembly;

    front angle means for defining the disposition of a leading portion of each coil with respect to the normal line, said front angle means being greater than said back angle means; and

    means for noninvasively supporting the plurality of coils in an orientation for controlling the blocking of electromagnetic waves, for radial loading of the radial garter-type canted-coil spring and for controlling the resilient characteristics of the radial garter-type canted-coil spring.
