ABSTRACT

The magnetron was invented by A. Hall [1] in 1921 as a power converter and power regulation device. In 1928, two Japanese professors, Yagi and Okabe, found that a magnetron, in which the anode was cut into two or more segments, could generate high frequencies. The multiresonator magnetron was created in 1936 by Soviet engineers N.F. Alekseev and D.E. Malyarov and was described in 1940 in the press [2]. Around the same time, H. Booth and D. Randall developed a similar design in the UK. The successful use of these devices during the Second World War for radar stations caused a rapid development of theoretical and experimental research, as well as work on the practical use of magnetrons [3-7]. Such advantages as high efficiency, amplitude and frequency stability, durability, small weight dimensions and cost, characteristic for classical magnetrons and devices based on them, predetermined interest to them from relativistic high-frequency electronics [8].
