Abstract :
The nonlinear interaction of transversely bounded terahertz pulses with layered structures that include graphene layers is investigated theoretically. The nonlinearity possesses the focusing character both in longitudinal and transverse directions. There exist the optimum input amplitudes and transverse widths of the input pulse to get the maximum pulse compression.
