英文摘要： Very recently, surface plasmon polaritons (SPPs) have attracted much attention due to its unique characteristics and promising potential applications. The proposal which investigates both SPPs and Airy beams is concentrated on the following three parts: (1) Using Finite-Difference Time-Domain method and Finite element method, etc., we study the formation and the propagation of plasmonic Airy beams; (2) We derive the spatiotemporal equations of plasmonic Airy beams in the presence of the linear potential. The propagation of the Airy beams is modulated by the linear potential; (3) We also study the dynamical behavior of the plasmonic Airy beams by introducing the nonlinear potential. The aims by performing the proposal are listed in the following: (1) We will be able to modulate the properties of the plasmonic Airy beams, such as the self-bending and self-healing, etc.; (2) We plan to achieve some exotic optical phenomena, such as light bullets, and we will uncover their physical mechanisms; (3) We will understand the mechanism of how does the nonlinear potential influence the plasmonic Airy beams. This proposal is helpful to understand the mechanism of exotic optical phenomena, it has profound physical meanings. We believe this proposal plays an important role both in the basic researches and applications.
