| 相关介绍： | 报告摘要：In this talk, the speaker will present two stability results of logarithmic type in determining conducting scatterers by a minimal number of electromagnetic (EM) far-field measurements. The admissible Lipschitz scatterers are of general polyhedral type, which may consist of finitely many (with an unknown number) solid polyhedra and screen-type cells. They satisfy minimum regularity assumptions. For the general case, the stability estimate is established by using two EM far-field measurements. If there are no screen-type components presented, then the stability estimate is established by using only a single far-field measurement.
