The research of interaction between light fields and microstructures has prompted people to discover new physical properties, put forward new theories and further produce new technologies, greatly promoting the development of photonic technology and its application in physics, information science, biomedicine, material science and other fields. The aim purpose of this project is to construct new multi-dimensional structured light fields and enrich the interaction between light fields and materials. We precisely construct special surface waves with modulated parameters based on the coherent controlling of the surface plasmon polariton (SPP) and evanescent field, and study the interaction of these new surface waves with dielectric/metal nanostructures. On the one hand, put forward the principle and method for the precise detection of surface waves by analyzing the local and far-field scattering fields that correlate with the the interaction; on the other hand, propose the technology for precisely control the near-field optical force and torque, by engineering the surface wave and steering the interaction. The main contents in this project include: 1. The construction and modulation of structured surface waves; 2. The detection of parameter structure of the structured surface waves; 3. The novel optomechanical effect of structured surface waves. The research progresses would not only provide a new method for the modulation of the surface coherent field, but also supply some physical bases for the generation, detection and modulation of the nano- and deep sub-wavelength scale local fields. The new phenomena and effects emerging from the interaction between structured surface waves and nanomaterials would also promote new functional devices.
