报告摘要:

The scattering and inverse scattering of acoustic and electromagnetic waves are important subjects in many engineering and scientific fields. There are many challenges in their mathematical analysis and numerical computation.  

Near-filed optics is a subject to study some near-field phenomena including non-radiating field and evanescent wave in optics. Near-field optical microscopes and near-field scanning optical microscopes are important instruments based on principle of near-field optics. They are such imaging systems with superresolution. In general, for ordinary optical imaging system, the resolution is limited by half wave-length of illustrate light. But for near-field imaging systems, this limit can be broken due to using the information from evanescent waves. 

In this talk, we are going to show our studies on numerical computation for a kind of scattering and inverse scattering problems which are from near-field optics.
