Jules Fejer
Jules Fejer (; January 22, 1914 – December 21, 2002) was a Hungarian physicist. Fejer was born in Budapest, Austria-Hungary. In the late 1950s he wrote a fundamental paper on incoherent backscatter, explaining why the width of the backscattered echo was determined primarily by the ion thermal velocity rather than by the electron thermal velocity. He was one of a group of ionospheric physicists brought together by Henry G. Booker to start what became the Electrical and Computer Engineering department at the University of California, San
of Signals which was engaged in developing South Africa's own radar system based on the British experience which had been communicated to them. Wadley and other colleagues including Jules Fejer, the Hungarian-born mathematician, were trained on the British RADAR project. His association with Fejer would continue for many more years. Wadley was not keen on mathematics but Fejer proved each of Wadley's concepts mathematically.
In 1946, Wadley was employed as a designer of radio equipment and instrumentation in a special division of the Telecommunications Research Laboratory (TRL
