Abstract : A load impedance intrusion detection system uses the physical object to be protected as an integral part of the systems. The physical object itself is sensitive to any attempt to violate its physical integrity by using it as an electrical termination to a conduit of electromagnetic energy thus establishing a zone of protection by means of near field electromagnetic energy surrounding the physical object itself.
