Modification of tunneling rates as a function of the field amplitude is calculated. Nonlinear dependence on the ac field strength is reported for the conductivity of two-dimensional electron gas. It develops a periodic peak structure.9 pages, 4 figuresMesoscale and Nanoscale PhysicsQuantum Physicstext
