表面等离极化激元在片上信号传输、增强非线性/拉曼效应、生物/化学传感、超分辨成像等方面具有重要应用. 在这些应用中, 表面等离极化激元的近场传输及远场散射起着重要作用.然而，人们强烈希望了解这些物理效应。本文首先简要回顾了SPP的发展历史和研究进展。接下来，我们将重点讨论SPP的近场传播和远场散射，包括它们的基本理论和实际应用。最后，我们回顾了几种不同的操纵SPP近场波前的方法。 基于这些进展, 人们对表面等离极化激元的散射特性有了更为深刻的理解和更加强大的调控能力, 这将对未来表面等离极化激元相关研究和应用带来启发.
Surface plasmon polaritons (SPPs) have found many important applications in on-chip signal transportation, enhanced nonlinear/Raman effect, biological/chemical sensing, super resolution imaging, etc. In these applications, the near-field propagation and far-field scattering of SPPs play a vital role. However, there has been strong desire to understand these physical effects. In this paper, we first briefly review the history and progress of SPPs. Next, we mainly focus on the near-field propagation and far-field scattering of SPPs, including their fundamental theories and practical applications. Finally, we review several different approaches to manipulating the near-field wavefronts of SPPs. These researches offer us a more in-depth understanding and the ability to more strongly control the scattering characteristics of SPPs, which may promote the scientific researches and practical applications of SPPs in the future.
