Waves in Complex Media: Theories and Applications

Overview

Abstract

Our group is dedicated to multidisciplinary areas that are related to wave.  We focus on the theoretical modeling and numerical simulation of classical wave propagation in complex systems, such as periodic structures and random media.  In this talk, I will give an overview of the research conducted in our group by emphasizing on three major aspects:  numerical method, homogenization, and applications in artificial materials.  First, I will briefly introduce the numerical methods we are employing by focusing on the T-matrix method, in which full multiple scatterings are taken into account.  In conjunction with fast algorithms, the T-matrix method is a powerful tool to solve wave equations in a complex medium with a large number of scatterers.  Second, I will review the developments on homogenization.  Homogenization, or effective medium theory, has been widely used in various domains. We endeavor to develop proper effective theory that can significantly reduce the complexity of the problem without losing the essence of the physics.  Finally, I will demonstrate the applications of both numerical methods and homogenization in designing new artificial materials with intriguing properties. Several illustrative examples will be presented.
