Abstract

The possibility of propagation of a plane solitary electromagnetic wave in the plane of a square two-dimensional graphene-based superlattice at various angles to its axes is investigated. A nonlinear equation describing the vector potential of a solitary electromagnetic wave is obtained for the case of weak nonadditivity of the energy spectrum of charge carriers in the collisionless approximation. It is shown that the propagation of plane solitary waves is possible either along the axes of the superlattice or at an angle of 45° to them.
