应数学系郭玉坤副教授的邀请，中国科学院数学与系统科学研究院应用数学研究所刘晓东副研究员将于近日来访我系并做报告，欢迎感兴趣的师生来参加，下面是报告的详细信息。 时间： 2016 年7月27日下午16：00-17：00 地点： 数学系会议室（格物楼503） 题目：Inverse Scattering by cavities 摘要: In this talk, we introduce a new kind of inverse scattering problems, i.e., the interior inverse scattering problems of reconstructing the boundary of a cavity. These problems occur in many industrial applications of non-destructive testing where both the sources (incident waves) and measurements (scattered waves) are inside the cavity. It is important to test the structural integrity of the cavity using acoustic or electromagnetic waves emitted and measured by sources and receivers placed on a curve inside the cavity . Thus, an interior scattering problem arises. We will introduce our recent work on this fairly new research topic. Both the uniqueness theory and the numerical methods will be mentioned in this talk. 简介：刘晓东副研究员，中国科学院数学与系统科学研究院应用数学研究所。刘老师本科毕业于北京师范大学数学科学学院，博士毕业于中科院数学与系统科学研究院，师从著名计算数学专家张波研究员，主要研究领域为声波电磁波正反散射问题和反边值问题的分析与计算。刘晓东博士曾获国家自然科学基金青年基金和面上基金以及德国洪堡基金会博士后奖学金，曾在SIAM Journal on Applied Mathematics，Inverse Problems等期刊发表SCI论文20余篇。 |
