ResumoNonlinear THz reflection by a superlattice is calculated using an effective dielectric function. Oscillations of the reflection coefficient with the electric field amplitude signifies dynamic electron localization. The nonlinear connection between the incident and internal fields leads to a reflection coefficient exhibiting hysteresis as a function of the incident field.
