【摘要】 Accelerating beams with intensity cusps and exotic topological properties are drawing increasing attention as they have extensive uses in many intriguing fields.We investigate the structural features of accelerating polygon beams,show their generalized mathematical form theoretically,and discuss the even-numbered polygon beams.Furthermore,we also carry out the experiment and observe the intensity evolution during their propagation.
