Dr. Sami Gopalsami Biography

Nachappa “Sami” Gopalsami received his B.E. and M.S. degrees in Electrical Engineering from the University of Madras, India and Ph.D. degree in Electrical Engineering from the University of Illinois, Chicago. He joined Argonne National Laboratory in 1980 where he is a senior scientist in the nuclear engineering division. His research interests include development of radio frequency, microwave, millimeter-wave, and terahertz sensors and imaging systems for national security, medical, environmental, and nondestructive evaluation applications.

Dr. Gopalsami has published over 150 peer-reviewed and conference papers in the area of sensors and Nondestructive evaluation and has 11 U.S. patents. He has received two R&D 100 awards from the Research and Development Magazine, both on millimeter wave sensors in 1986 and 2007; an outstanding paper award from the American Society of Nondestructive Testing; and an Outstanding Mentor award from the Department of Energy Office of Science Undergraduate Research Programs. He is a Fellow of IEEE and a member of Sigma Xi and SPIE.

 

 

Abstract:

Sensing and imaging systems abound in the electromagnetic spectrum from RF to THz for many applications including automotive, industrial, medical, environmental, and national security sectors. These applications exploit the physics of interaction of electromagnetic waves with materials, which depends on the variation of the material’s reflection, absorption, and scattering properties as a function of wavelength. Different physics come into play as the wavelength varies from meters to micrometers and the photon energy varies from micro eV to milli eV. This talk will give an overview of electromagnetic sensing and imaging research at Argonne for in-situ, standoff, and remote sensing applications. In particular, remote sensing systems in the millimeter wave spectrum will be described, which are more effective for persistent monitoring in optically obscuring conditions such as when it is cloudy, dusty, smoky, day, or night.
