We theoretically propose and numerically investigate an active plasmonic device made up of a nonlinear {epsilon}-near-zero metamaterial slab of thickness smaller than 100 nm lying on a linear {epsilon}-near-zero metamaterial substrate. We predict that in free-space coupling configuration the system operating at low intensity displays plasmon mediated hysteresis behavior. The phase difference between the reflected and the incident optical waves turns out to be multivalued and dependent on the…
