1. A method of isolating the shield of a shielded conductor system from a low frequency power source to which the shield may be coupled, and for shielding the field within the conductor system from ambient high frequency electromagnetic interference, comprising:

  • providing an interruption in the shield; and

    filling the interruption with dielectric and magnetically absorptive material selected and disposed to create a capacitive coupling across the interruption to isolate the shield and magnetic absorption within the interruption to absorb energy associated with the ambient electromagnetic interference.
