Abstract
A system includes a source of electromagnetic energy or power and an amplitude-sensitive circuit. An amplitude-limiting transmission line couples the source to the circuit. The transmission line includes a semiconductor in the field of the transmission line and a light source for illuminating the semiconductor with light responsive to the amplitude from the source. Application of energy or power to the light source illuminates the semiconductor, which produces a plasma. The plasma tends to attenuate the energy or power reaching the circuit.
