We study the propagation of Airy beams in transversely linear index potentials with a gradient that is dynamically changing along the propagation direction. We find exact solutions in the case of Airy and apodized (Gaussian and exponentially) Airy beams in 1+1 and 2+1 dimensions. More important, we find that the Airy beam can follow any predefined path, in which case the potential gradient is determined as a function of this path.
我们研究了在沿传播方向动态变化的横向线性折射率势中艾里光束的传播。我们在 1+1 和 2+1 维的情况下找到了艾里光束和调变（高斯和指数）艾里光束的精确解。更重要的是，我们发现艾里光束可以遵循任何预设的路径，在这种情况下，势梯度被确定为该路径的函数。
