CENTER FOR COMPUTATION & TECHNOLOGY

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 first give a brief introduction to metamaterials, then I'll focus on the mathematical study of some cloak models. Numerical simulations using finite element methods in both frequency domain and time domain will be presented. Some open issues will be mentioned at the end of my talk.

Jichun Li is a Full Professor of Mathematics at the University of Nevada, Las Vegas (UNLV). He earned his B.S. in Computational Mathematics from Nanjing University and his Ph.D in Applied Mathematics from Florida State University . He worked 2 years (1998-2000) at ICES of University of Texas at Austin before he moved to UNLV in 2000. He was a summer faculty researcher at the U.S. Air Force Research Laboratory from 2003-2006. During August 2008 - July 2009, he served as Associate Director for the Institute for Pure and Applied Mathematics (IPAM) at UCLA.

Dr. Li is very interested in multidisciplinary research related to numerical analysis and scientific computating. His major research areas are on numerical methods (mainly FEM) for PDEs from different disciplinaries. His work includes singularly perturbed problems, surface and groundwater modeling, parallel computing with MPI and C++, image processing, radial basis meshless methods, inverse problems, high-order compact difference schemes, and Maxwell's equations in metamaterials. His research has been supported by the Air Force, NSF, NSF EPSCoR, and NASA EPSCoR.
