报告题目:  Uniqueness in phaseless inverse scattering problem with superposition of incident waves

报告内容:  

In this talk, we will establish several uniqueness results in inverse acoustic and electromagnetic scattering problems with phaseless data. The main difficulty is the so-called translation invariance of phaseless far-field data. Our idea comes from the fact that the translation invariance can be broken if superpositions of two plane waves are chosen as the incident field. Motivated by this idea, we establish the first general uniqueness result with phaseless far-field data corresponding to superposition of two incident plane waves. Moreover, a similar uniqueness result based on superposition of two incident point sources can be proved. Recently, we extend our uniqueness result to the case of phaseless near-field data corresponding to superposition of two incident plane waves. This talk is based on a joint work with Bo Zhang and Haiwen Zhang.
