    报告摘要:In the June 23, 2006's issue of Science magazine, Pendry et aland Leonhardt independently published their papers on electromagneticcloaking. In Nov.10, 2006's Science magazine, Pendry et al demonstratedthe first practical realization of such a cloak with the use of artificially constructed metamaterials. Since then, there is a growing interest in using metamaterials to design invisibility cloaks. In thistalk, I will first give a brief introduction to invisibility cloaks with metamaterials, then I will focus on some time-domain cloaking models. Well-posedness study and time-domain finite element method for thesemodels will be presented. Finally, I will show some numerical simulations of time-domain cloaking and optical black holes. I will conclude the talk with some open issues.
