Abstract :
A time resolved study of the THz plasmon dynamics in a random metallic ensemble is presented. This investigation is performed via a THz pump-THz probe experiment. It is illustrated that the electric field of the transmitted THz probe pulse shows an enhancement when the metallic ensemble is first excited by means of a THZ pump pulse. The effect is studied versus the temporal delay of the probe pulse with respect to the pump pulse.
