Shuleikin, Mikhail

Born Oct. 21 (Nov. 2), 1884, in Moscow; died there July 17,1939. Soviet specialist in radio engineering. Academician of the Academy of Sciences of the USSR (1939).

After graduating from the St. Petersburg Polytechnic Institute in 1908, Shuleikin remained there to study radio engineering and to teach. He was employed at the radio-telegraph plant of the Naval Administration from 1913 to 1918, when he entered the Red Army as a brigade engineer. He headed the radio engineering laboratory of a military engineering directorate from 1918 to 1921.

In 1919, Shuleikin was named a professor at the Moscow Higher Technical School, where he founded a radio engineering division. He became a professor at the Institute of the National Economy in 1921 and concurrently taught at other educational institutions. Shuleikin served as chairman of the Society of Radio Engineers from 1919 to 1929 and was appointed head of the radio communications commission of the Academy of Sciences of the USSR in 1938.

Shuleikin was the author of a number of seminal works on radio-wave propagation. He investigated the effects of the upper layers of the atmosphere on radio-wave propagation and derived formulas for calculating the propagation of radio signals along the surface of the earth. He developed a theory of long-wave antennas as well as techniques for their design. Shuleikin published several works on radio engineering and in 1916 pointed out the existence of side bands in amplitude-modulated radio-frequency oscillations.
