We are mainly interested in the study of forward and inverse scattering problems. We are currently developing fast algorithms to solve forward scattering problems. In inverse scattering problems, we apply scattering algorithms to enable inverse imaging from the measured field data. The following clickable map leads you to some results of our current work.

Research Statement:

Prof. Chew's current research interest is in fast computational algorithms for solving electromagnetic scattering problems. His other areas of research interest are in wave propagation, scattering, inverse scattering, inhomogeneous media for geophysical subsurface sensing and nondestructive testing applications and experiments. He has designed experiments with his graduate students to demonstrate the super-resolution phenomena of nonlinear inverse scattering. Working with his research scientists, postdocs and students, his research group has solved electromagnetic scattering problems of unprecedented sizes involving 10 million unknowns using fast algorithms and matrix-free methods. He is the originator of several fast algorithms for solving electromagnetics scattering and inverse problems, and has authored a book, Waves and Fields in Inhomogeneous Media, in addition to more than 210 scientific journal articles and 300 conference papers, several patents, and book chapters. His work is widely cited. Prof. Chew is an IEEE Fellow and was named an NSF Presidential Young Investigator in 1986. Presently, he is the director of the Center for Computational Electromagnetics and the Electromagnetics Laboratory. Prof. Chew has been named frequently to the Daily Illini's "Incomplete List of Excellent Instructors." He is also the winner of the IEEE Year 2000 Graduate Teaching Award, and a Founder Professor of the College of Engineering at the University of Illinois. Before coming to University of Illinois, Prof. Chew was a department manager and program leader at Schlumberger-Doll Research.
