Electromagnetic wave circuit disruptor and method

A method of disrupting an electromagnetic wave circuit comprising the steps of:

• (a) providing 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) providing 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) providing 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) providing a controller connected to a 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.

A method of disrupting an electromagnetic wave circuit using a biasable non-reciprocal device having terminals for receiving and transmitting the electromagnetic signals wherein the electromagnetic signals propagate around a circulator terminals in a first direction when the circulator is biased to operate in a first mode and the electromagnetic signals propagate around the circulator terminals in a second direction when the circulator is biased in a second mode, comprising the steps of:

• (a) providing a circuit which operates at a nominal energy level at a select one terminal of the biasable non-reciprocal device;
• (b) detecting an inappropriate amount of electromagnetic wave energy at the select one terminal, the inappropriate amount of electromagnetic wave energy being substantially larger than the nominal energy level of the circuit;
• and
• (c) in response to the detecting step, biasing the non-reciprocal device to operate in a mode which causes the electromagnetic signals to propagate in a direction which mitigates damage to the circuit.
