9/16/2009 - ARLINGTON, Va. -- Researchers funded by the Air Force Office of Scientific Research (AFOSR) at the University of Michigan invented a new type of magnetron that may be used to defeat enemy electronics. A magnetron is a type of vacuum tube used as the frequency source in microwave ovens, radar systems and other high-power microwave circuits.
According to Dr. Ron Gilgenbach, an AFOSR-sponsored researcher at the University of Michigan, a new class of magnetrons was invented that holds the potential for more compact Department of Defense microwave sources with faster start-up, as well as higher peak and average power.
"This invention should make it possible to develop more compact magnetrons that operate at higher power and higher frequencies," said Gilgenbach. "Higher power magnetrons could be utilized to jam and defeat enemy electronics."
