Abstract

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

二维石墨烯基超晶格平面上孤电磁波任意方向传播的可能性

研究了平面孤立电磁波在二维石墨烯基方形超晶格平面上以不同角度传播的可能性。在无碰撞近似下，对载流子能谱弱不可加性的情况，得到了描述孤立电磁波矢量势的非线性方程。结果表明，平面孤波既可以沿超晶格轴传播，也可以与超晶格轴成45°角传播。
