The theory of the anti-maser: coherent perfect absorption of RF

ORAL

Abstract

The radio frequency (RF)-analogue of the anti-laser is developed using four terminal network theory combined with the telegrapher's equation. We describe solutions of the Coherent Perfect Absorption (CPA) condition that are interpretable as the slab dielectric anti-laser. We find a host of other solutions, some of which have no simple optical analogue. Broadband solutions are found which hint at the possibility of a new type of asymmetric transient CPA phenomenon, and point out that this study suggests a potentially new low loss, reversible RF devices.
