报告摘要：We discuss some fundamental physics problems in the nano-optics, that include the interference of the surface plasmon waves, the transient surface plasmon polariton, the diffraction of a metal slit, the modelling of the metallic near-field imaging superlens and the optical radiation force on the nano-particle in the highly focused beams. Our contributions to nano-optics are not only based on the popular numerical solutions by the finite difference in time domain (FDTD), the finite element methods (FEM), but also on the generalized Lorentz-Mie scattering theory with the T-matrix and the mathematics for analytical solutions of the Maxwell’s equations, which provide more physical insight. The developed theory may be useful in the design of nano-photonics devices, nano-lithography and optical manipulation on the nano-particels and biological cells.
