Disclosed herein is an electromagnetic wave circuit disruptor apparatus suitable for disrupting the action of electromagnetic signals, the apparatus including: a biasable non-reciprocal device having terminals for receiving and transmitting the electromagnetic signals wherein the electromagnetic signals propagate around the non-reciprocal device terminals in a first direction when the non-reciprocal device is biased to operate in a first mode and the electromagnetic signals propagate around the non-reciprocal device terminals in a second direction when the non-reciprocal device is biased in a second mode; a controllable biaser coupled to the non-reciprocal device so as to bias the non-reciprocal device to operate in one of the first mode and second mode; a signal detector connected to at least one terminal of the non-reciprocal device to detect the electromagnetic signals at the at least one terminal; and a controller connected to the signal detector and the controllable biaser to selectively reverse the bias of the controllable biaser upon the detection of a condition in the electromagnetic signals at the at least one terminal, thereby causing the electromagnetic signals to propagate in a reverse direction so as to disrupt the action of the electromagnetic signals. The energy level at the receiver terminal of the non-reciprocal device is monitored to detect a condition such as an inappropriate amount of power at a circuit, such as receiver circuitry. When a failure mode is detected the bias of the controllable biaser is reversed, thus reversing the direction of the non-reciprocal device. Instead of flowing into the circuit, energy flows into a properly matched load on a provided terminal of the non-reciprocal device and is dissipated. |
