Computational Electromagnetics (CEM) in the 21st Century

2:00 PM-4:00 PM
New Hampshire 2

The design and analysis of modern electronic devices that find applications in diverse areas, such as radar and Very Large Scale Integration of semiconductors, requires fast and accurate solutions of the Maxwell equations over complex domains. The problems to be solved typically exhibit a wide range of spatial scales and time scales rendering the existing methods of solution (which are, at best, second-order accurate) too costly or too inaccurate when applied to problems of current and near future interest (e.g., modeling of the interconnections between logic elements inside CPU's whose clock speed exceeds 1 GHz). The speakers will review existing approaches, and will present their efforts towards the development of fast and highly-accurate computational methods to replace the standard techniques of CEM in the next century. Because of their experience with Industrial problems, the speakers will also elucidate the engineering perspective necessary for success.
