 Why
do you think your paper is highly cited?
|
“...this paper describes new terahertz sensing and imaging technologies which will impact Materials Science.”
|
|
THz wave (T-ray) technology has the potential to impact an almost
limitless number of interdisciplinary fields, including
communications, microelectronics, imaging, medical diagnosis, health
monitoring, environmental control, agriculture, forensic science,
and chemical and biological identification.
Does
it describe a new discovery or new methodology that's useful to
others?
Yes, this paper describes new terahertz sensing and imaging
technologies which will impact Materials Science.
Could
you summarize the significance of your paper in layman's terms?
We reviewed modern THz systems with an emphasis on several
promising new materials for THz generation and described the most
significant current and potential applications of THz systems. These
applications include tomographic imaging of dry dielectric
substances, label-free genetic analysis, cellular level imaging,
chemical and biological sensing, and material characterization .
How
did you become involved in this research?
I was a graduate student in Professor Arto Nurmikko’s group at
Brown University in the early 1980s. My Ph.D. thesis concerned the
use of picosecond lasers to test semi-magnetic, semiconductor
quantum wells. After I received my Ph.D., I worked in Dr. Ravi Jain’s
group at the Amoco Research Center. Our objective was to develop
picosecond electro-optic sampling test beds for semiconductor IC
circuits. In the late 1980s, I joined Prof. David Auston’s group
at Columbia University and began my THz research career.
