Abstract
The article is devoted to the study of optical properties of curved graphene and analysis of prospects for its use as an optical nanoanten-na. The studies were carried out by means of the quantum theory of response of the electronic population to external radiation and the density functional theory in the tight-binding scheme for approximation. The object of this study is the armchair graphene nanoribbon. During the study, it is revealed the presence of several additional peaks in the spectrum of the optical conductivity of curved graphene, which are not found in the plane graphene, in a case of waviness with amplitude of 0.4 nm and above. It is found that the magnitude of the waviness amplitude does not affect the position of the peak with maximum conductivity.
