Abstract: In the June 23, 2006's issue of Science magazine, Pendry et al and Leonhardt independently published their works on electromagnetic cloaking. In Nov 2006's Science, Pendry et al demonstrated the first practical realization of such a cloak with the use of artificially structured metamaterials. Since then, there is a growing interest in using metamaterials to construct invisibility cloaks. In this talk, I'll focus on the mathematical derivation and modeling of cloaking structures. Interesting simulations in both frequency domain and time domain will be presented. Some mathematical issues (such as using superconvergence for our adaptive method) will be mentioned during the talk.
