Design of metamaterials using transformation physics
M
etamaterials are rationally designed artificial materials composed of tailored functional building blocks densely packed
into an effective (crystalline) material. While metamaterials historically are primarily thought to be associated with
negative refractive indices and invisibility cloaking in electromagnetism or optics, it turns out that the simple metamaterial
concept also applies to many other areas of physics namely the thermodynamics, classical mechanics (including elastostatics,
acoustics, fluid dynamics and elastodynamics) and in principle also to the quantummechanics. This lecture will review the basic
concepts and analogies behind the thermodynamic, acoustic, elastodynamic/elastostatic, and electromagnetic metamaterials
and differences among them. It will provide an overview of the theory, the current state of the art and example applications
of various types of metamaterials. The review will also discuss the homogeneous as well as inhomogeneous metamaterial
architectures designed by coordinate-transformation-based approaches analogous to transformation optics. The application
examples will include laminates, thermal cloaks, thermal concentrators and inverters, anisotropic acoustic metamaterials,
acoustic free-space and carpet cloaks, and mechanical metamaterials with negative dynamic mass density, negative dynamic
bulk modulus, or negative ph ase velocity. Finally an example of quantum-mechanical matter-wave cloaking will be provided.
Biography
Professor Ramesh K. Agarwal is the William Palm Professor of Engineering at Washington University in St. Louis. From 1994 to 2001, he was the Sam Bloom-
field Distinguished Professor and Executive Director of the National Institute for Aviation Research at Wichita State University in Kansas. From 1978 to 1994, he
worked in various scientific and managerial positions at McDonnell Douglas Research Laboratories in St. Louis. He became the Program Director and McDonnell
Douglas Fellow in 1990. Dr. Agarwal received Ph.D in Aeronautical Sciences from Stanford University in 1975, M.S. in Aeronautical Engineering from the University
of Minnesota in 1969 and B.S. in Mechanical Engineering from Indian Institute of Technology, Kharagpur, India in 1968. He is the author and coauthor of over
600 publications and serves on the editorial board of 20+ journals. He has given many plenary, keynote and invited lectures at various national and international
conferences worldwide. He is a Fellow of AAAS, ASME, AIAA, IEEE, SAE and SME.
