▎ 摘　　要

We continue the study of surface corrugations influence on the monolayer graphene local electromagnetic response in Lerahertz range we started earlier. The effects of radiative decay, double valley structure of charge carriers spectrum in graphene and the "breathing" corrugated surface form induced synthetic electric fields are taken into account. To fulfill this program the generalized nonlinear self-consistent-field equation is obtained. In case of weak external alternating electric field (E) over right arrow (ext) (t) = (E) over right arrow (0) cos omega t for the obtained equation in linear approximation on the external electric field the exact solution is found It shows that in this case we get local induced current paths depending on the surface form z = h(x, y). This theoretical result qualitatively explains the corresponding experiments with local current patterns depending on the point by corrugations influence. The induced currents formula was obtained without using fully quantum approach which is necessary for theoretical description of such phenomenon in graphene nanoribbons. Besides the formulae obtained in the present paper could become the basis of the new method of the imaging of surface corrugations form for given experimental picture of local current paths.
