The Self-Healing Peculiarity of Airy Beams Propagation in Free-Space

摘要

We have theoretically and numerically investigated the self-healing peculiarity of Airy beams truncated by different decay factors. The self-healing dynamic processes of truncated Airy beams are different from that of blocked Airy beams. The wing with large truncation of Airy beam can propagate much longer distance than that of small truncated wing. When one of the wings is complete truncated, the Airy beam propagates along a straight line and neither self-bending nor self-reconstruction can be observed. The Poynting vector and energy flow are conducted to gain an insight into the physical mechanism.
