Goutam Chattopadhyay is a Senior Research Scientist at the NASA’s Jet Propulsion Laboratory, California Institute of Technology, and a Visiting Associate at the Division of Physics, Mathematics, and Astronomy at the California Institute of Technology, Pasadena, USA. He received the Ph.D. degree in electrical engineering from the California Institute of Technology (Caltech), Pasadena, in 1999. He has more than 300 publications in international journals and conferences and holds more than fifteen patents. He received the IEEE MTT-S Graduate Fellowship Award in 1997 and the best journal paper award in 2013 by IEEE Transactions on Terahertz Science and Technology. He also received more than 30 NASA technical achievement and new technology invention awards. He is an associate editor of the IEEE Transactions on Antennas and Propagation, a Fellow of IEEE (USA) and IETE (India) and an IEEE Distinguished Lecturer.


For more than last forty years, terahertz components and instruments have primarily been developed for space science applications in radio astronomy and planetary sciences. However, in recent years, terahertz waves are increasingly being used in commercial applications such as high speed communications, security imaging, autonomous landing and refueling of airplanes, and medicines. In spite of all these fascinating scientific and commercial potential, the terahertz frequency range (loosely defined as 300 GHz < ν < 10 THz) still remains one of the least utilized electromagnetic bands because of the unavailability of commercial source and sensor components, and sub-systems.

In this presentation, an overview of the state of the terahertz technology will be presented. The talk will detail the science and other applications that specifically require technology at terahertz frequencies. The challenges of the future generation instruments, detectors, and antennas at these frequencies in addressing the needs for critical scientific and commercial applications will also be discussed.
