Electromagnetic response of graphene. — •Sergey Mikhailov and Klaus Ziegler — Institute for Physics, University of Augsburg, 86135 Augsburg, Germany

Recently discovered new carbon based material - graphene - demonstrates a number of interesting and unusual transport and optical properties. Our recent predictions of a new transverse electromagnetic mode in graphene [1] and of its strongly non-linear electromagnetic behavior [2] shows that this material can be used in terahertz electronics for higher-harmonics generation at microwave and terahertz frequencies. In this work we study the influence of the self-consistent field effects, the radiative decay and the scattering on the non-linear electromagnetic response of graphene, and find the optimal experimental conditions, under which the higher harmonics generation effect can be observed in this material.
