Antennas Guest Speaker Seminar: Test and measurement equipment to 1THz - from devices to system modules
Presenter Dr Thomas W. Crowe, Virginia Diodes, Inc., Charlottesville, Virginia, USA
The talk will begin with brief reviews of Virginia Diodes Inc. and the many applications of terahertz technology. This will be followed by a description of the diode and circuit technologies that have allowed the development of sources, detectors and receivers through out the frequency range from 50GHz through 3THz. I will then show how these building blocks are used to create test and measurement systems; including frequency extenders for signal generators, signal analyzers and vector network analyzers.
Dr. Crowe received the B.S. (Physics) from Montclair State College (1980), and the M.S.E.E. degree (1982), and the Ph.D. from UVa (1986). He joined the faculty as Research Assistant Professor of Electrical Engineering in 1986, and was promoted to Research Professor in 1997. He served as the Director of the Semiconductor Device Laboratory from 1987 through 2003. He has authored over fifty referred publications and well over one hundred conference proceedings papers. He has also presented numerous invited talks throughout the US and Europe. While at UVa Dr. Crowe was a PI on $25M of sponsored research from NSF, NASA, JPL, NRAO, and the U.S. Army and Air Force, as well as private industry.
As Founder and CEO of Virginia Diodes, Inc., Dr. Crowe is striving to bring terahertz technology into the market-place. VDI is a thriving a small business that now employees over fifty people, including eight PhDs. VDI has supplied terahertz devices, components and subsystems to a growing customer base totaling several hundred companies, research laboratories and universities throughout the World. VDI generates over 90% of its annual revenue from the sales of terahertz products, with the remainder supported by research contracts. VDI has recently delivered LO sources for radio-astronomical receivers operating as high as 2.7THz. The main focus of VDI product development is now advanced test and measurement equipment for the frequency range from 50GHz through 1.1THz.
