摘要：
The dynamics of Airy beams modeled by the fractional Schrödinger equation (FSE) with the potential barrier are numerically investigated. Adjusting the Lévy index provides a convenient way to control the diffraction of Airy beams which presents the non-diffraction and splitting property. It has been found that the total reflection of beams occurs when the depth of the single potential barrier exceeds the threshold, and that the number of reflected waves is influenced by the Lévy index and the location of potential barrier. However, the periodic self-imaging phenomenon of Airy...
