In this paper, we investigate the evolution of electromagnetic waves in a nonlinear anisotropic optical medium with carbon nanotubes (CNTs). Based on Maxwell’s equation, an effective equation is obtained for the vector potential of the electromagnetic field, which takes into account different values of the velocity and polarization with two directions. The dependence of the pulse shape on the crystal type, as well as the angle between the electric field and the CNTs axis is revealed.

具有碳纳米管的各向异性光学介质中超短光脉冲的传播

在本文中，我们研究了具有碳纳米管 (CNT) 的非线性各向异性光学介质中电磁波的演变。基于麦克斯韦方程，得到了电磁场矢量势的有效方程，该方程考虑了两个方向的速度和极化的不同值。揭示了脉冲形状对晶体类型的依赖性，以及电场与 CNT 轴之间的角度。
