Patent ID: 8411601

Claim:
An electromagnetic wave circuit disruptor apparatus suitable for disrupting the action of electromagnetic signals, the apparatus comprising: (a) a biasable non-reciprocating device having terminals for receiving and transmitting the electromagnetic signals wherein the electromagnetic signals propagate around the non-reciprocating device terminals in a first direction when the non-reciprocating device is biased to operate in a first mode and the electromagnetic signals propagate around the non-reciprocating device terminals in a second direction when the non-reciprocating device is biased in a second mode; (b) a controllable biaser coupled to a circulator so as to bias the non-reciprocating device to operate in one of the first mode and second mode; (c) a signal detector connected to at least one terminal of the non-reciprocating device to detect the electromagnetic signals at the at least one terminal; and (d) a controller connected to the signal detector and the controllable biaser to selectively reverse the polarity of the controllable biaser in response to the detection of a condition in the electromagnetic signals at the at least one terminal.
