Institute of Standards and Technology, R.F. Technology Division, Boulder CO. Date : Saturday March 1 2003. What we saw: In a show of support for the RMCEMC, three scientists from the National Institute of Standards & Technology, RF Technology Division located at Boulder, CO gave up one of their weekend days to present at the IEEE Denver Technical Symposium. First up was Robert Johnk with "Ultrawideband Metrology at NIST". Bob presented a nice summary of the theory and some of the promise for ultrawideband measurement systems in that it is a single event that contains all the information of the unit under test. Gated properly it is possible to test in non-ideal test loactions and still make meaningful measurements. Some applications for Wideband Metrology are Precision Antenna Calibrations, characterizing scattering & propagation in measurement facilities and airframe shielding & cabin propagation. Next up was Chriss Grosvenor who presented “TEM Horn Antenna Design: Theory and Simulation." Integral to the Ultrawideband metrology technology is the TEM Horn Antenna and Chriss showed some of the design intricacies that can be modeled and measured to understand and build an efficient design. Last but not least was David Novotny with "Ultrawideband Diagnostic Imaging of EMC Facilities". Using this technology the accurate mapping of a test facility in a short period of time. Not only that - by studying the reflections - it is possible to pinpoint the location of site anomalies. |
