报告(一)题目:Recent Developments in Direct Sampling Methods for General Inverse Problems
报 告 人:Prof. Jun Zou (香港中文大学)

报告摘要:
      In this talk we shall review the recent developments in direct sampling methods for both nonlinear wave-type and non-wave type inverse problems. Some general motivations, principles and justifications are discussed for the choices of several key ingredients of the direct sampling methods, and numerical experiments are presented for various inverse problems.

报告摘要:
       In this talk we report some recent resonance analysis of electromagnetic metasurfaces. We consider the anomalous electromagnetic scattering by periodically distributed sub-wavelength plasmonic nanoparticles, and establish some quantitative representation of the field enhancement due to mixed collective plasmon resonances, which can be characterized by the spectra of periodic Neumann-Poincare type operators. Based on the far field analysis, we demonstrate theoptical effect of the electromagnetic metasurface can be effectively approximated by a Leontovich boundary condition. These results  confirm essential physical changes of metasurface at resonances mathematically.
