Terahertz Technology in Outer and Inner Space Slides

Dr. Peter H. Siegel, California Institute of Technology, Pasadena, CA


Abstract:  After more than 30 years of niche applications in the space sciences area, the field of Terahertz Technology is entering a true Renaissance.  While major strides continue to be made in submillimeter wave astronomy and spectroscopy, the past few years have seen an unprecedented expansion of terahertz applications, components and instruments.  Broad popular interest in this unique frequency domain has emerged for the first time, spanning applications as diverse as biohazard detection and tumor recognition.  Already there are groups around the world who have applied specialized Terahertz techniques to disease diagnostics, recognition of protein structural states, monitoring of receptor binding, performing label-free DNA sequencing and visualizing contrast in otherwise uniform tissue.  A commercial terahertz imaging system has recently started tests in a hospital environment and new high sensitivity imagers with much deeper penetration into tissue have begun to emerge.  Solicitations for more sophisticated instruments and enabling terahertz components have filtered into US agency proposal calls from DoD and NASA, to NSF and NIH, and many new research groups have sprung up, both in this country and in Europe and Asia.  This talk will broadly survey terahertz technology from its cradle applications in space science and spectroscopy to more recent biomedical and chemical uses.


Biography:  Peter H. Siegel obtained a BS in astronomy and physics from Colgate University, Hamilton NY in 1976, a Masters in Physics and a PhD in Electrical Engineering from Columbia University in 1978 and 1983 respectively. He has been involved in the analysis and development of millimeter-and submillimeter-wave sensors for nearly 30 years. He began his career in millimeter wave technology in 1975 as a summer student at the NASA Goddard Institute for Space Studies in New York City, working with astronomer Patrick Thaddeus and electrical engineer Tony Kerr on low noise receivers. In 1983 he moved up in frequency to the submillimeter, working as a National Research Council Fellow on THz planar antenna arrays. From 1984-87 Dr. Siegel was employed at the National Radio Astronomy Observatory where he worked with Sandy Weinreb and the millimeter wave receiver group in Charlottesville Virginia, maintaining the Kitt Peak National Radio Observatory. He moved to JPL in 1987 to work on advanced technology development for NASA astrophysics applications.
