Abstract
Disclosed herein is an electromagnetic wave circuit disruptor apparatus including: a biasable non-reciprocal device having terminals for receiving and transmitting the electromagnetic signals, a controllable biaser, a signal detector, and a controller connected to the signal detector and the controllable biaser to selectively reverse the bias of the controllable biaser. 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 at a receiver circuit. 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.
