ABSTRACT

We examine the transmission coefficient of plane waves across two nonlinear delta-function barriers with positive opacity. It is shown that this simple system is capable of bistable behavior at sufficiently large input intensities. The bistable behavior is centered around the first transmission resonances and is a simple example of a continuum nonlinear system that can display bistability without the presence of a feedback loop.
