Mikhail Samoilovich Neiman (March 7, 1905, in Sevastopol, Russian Empire – June 25, 1975, in Moscow, USSR) was a Soviet physicist, Doctor of Technical Sciences and professor.

The main directions of his research were the study of the ultra-high frequency electromagnetic systems, theoretical and applied radio engineering, and automatic processes.

In 1922 Mikhail Neiman graduated from Simferopol general education college, and in 1928 from the Physics and Mechanics faculty of the Leningrad Polytechnic Institute with specialty "Radio engineering" and qualification "engineer-physicist."

In 1926, being a student, he joined the Central Radio Laboratory (CRL) of the National Trust of electrical plants of the weak current.

In February 1941, Neiman in a group of experts was sent on an assignment by People's Commissariat of Electrical Industry to the United States under a technical assistance contract with a leading radio company RCA.

Under his leadership a number of research and development works were made: new methods for the generation, transmission and reception of microwave signals, the production of large capacities in the centimeter and decimeter ranges, constructive design of disk klystron and others.

Many people noted that even now Neiman is the example of real scientist, a wonderful teacher and a man of high moral character, and he serves as the guide for their work and life.

Proposed and developed a general theory and methods of calculation of closed oscillating electromagnetic devices, later known as the "volume resonators", which are the basis of many systems of UHF and SHF bands.

His monograph "Triode and tetrode microwave frequency generators"[3] was awarded the Stalin Prize of the 3rd degree in 1952 and published also in German and Chinese.

He developed the theory of transverse joints in waveguide systems, proposed a number of methods for design and analysis of triode, tetrode, pentode, klystron, platinotron, magnetron and reznatron amplifiers and oscillators, carried out studies of surface electromagnetic waves.

In 1964-65, Neiman published original ideas and principal considerations of radical miniaturization on elements for recording, storing and retrieving of digital information to the molecular-atomic level, including the use of structures similar to DNA molecules.

In 1966-67, Neiman generalized negentropy principle of information to digital data processing systems, and defined the relation restrictions between their speed and energy level of the functioning of their elements.
