WebWilliam C. Brown (May 22, 1916 – February 3, 1999) was an American electrical engineer who helped to invent the crossed-field amplifier in the 1950s and also pioneered microwave power transmission in the 1960s. Brown received his BSEE from Iowa State University in 1937, and his MSEE from the Massachusetts Institute of Technology in 1941. WebMar 20, 2012 · Crossed-field Amplifiers (CFAs) are a class of vacuum microwave devices where an applied direct current (DC) electric field is oriented perpendicular to a constant magnetic field. Typically, CFAs have a magnetic field oriented in an axial direction and an electric field applied around a circumference of a cathode.
