In recent years, there has been considerable thrust toward the development of finite-difference time-domain (FDTD) and finite-volume time-domain (FVTD) methods for the numerical solution of Maxwell equations for electromagnetic scattering from complex three-dimensional objects. Maxwell equations are written in conservation form and solved on a three-dimensional grid both inside and outside the scattering body. Higher-order spatial and temporal discretization are generally employed to obtain accurate solutions efficiently especially for large scattering bodies. An important aspect of the calculations is the formulation and implementation of the boundary conditions – both the radiation boundary condition (RBC) and the material interface boundary conditions in discretized form. Recent developments in boundary conditions formulations and implementations will be reviewed and critically examined. Three-dimensional examples including complete aircraft configurations will be presented to demonstrate the power of the FVTD approach.

Professor Ramesh K. Agarwal is the William Palm Professor of Engineering and the director of Aerospace Research and Education Center at Washington University in St. Louis. From 1994 to 2001, he was the Sam Bloomfield Distinguished Professor and Executive Director of the National Institute for Aviation Research at Wichita State University in Kansas. From 1978 to 1994, he was the Program Director and McDonnell Douglas Science and Engineering Fellow at McDonnell Douglas Research Laboratory (MDRL) in St. Louis. Dr. Agarwal obtained his Ph.D. from Stanford University in 1975. Since then, he has worked in Computational Fluid Dynamics (CFD), Computational Magneto-hydrodynamics and Electromagnetics, and Semiconductor Device Simulation. Dr. Agarwal is a Fellow of eight societies - American Association for Advancement of Science (AAAS), American Institute of Aeronautics and Astronautics (AIAA), American Physical Society (APS), American Society of Mechanical Engineers (ASME), Royal Aeronautical Society (RAeS), Society of Manufacturing Engineers (SME), Society of Automotive Engineers (SAE), and the Institute of Electrical and Electronics Engineers (IEEE). He has served as a distinguished lecturer of AIAA (1996-1999), ASME (1994-1997), and IEEE (1994-2005). He has received many honors and awards for his research contributions including the ASME 2001 Fluids Engineering Award and AIAA 2002 Sustained Achievement Award.
