Georgy Danilovich Maluzhinets
(1910 - 1969)

 

Georgy Danilovich Maluzhinets was born in 1910.

After his graduation from the Moscow State university (the department of Theoretical Physics), he began his studies in the theory of diffraction of acoustic and electromagnetic waves.

Before the outbreak of World War II, Malyuzhinets developed the theory of absorbing inhomogeneous media. The theory was used in the design of a layered coating with highly efficient acoustic absorption for the dome of the Big Hall of the Palace of Soviets (that was never built, though). For calculating the characteristics of this layered coating, Malyuzhinets proposed an original impedance-locus technique.

After the war, Malyuzhinets performed a series of studies concerned with the general theory of Sommerfeld integrals, the mathematical formulation of steady-state diffraction problems in arbitrary domains, and the new mathematical methods in the theory of diffraction.

The results of these studies were summarized by Malyuzhinets in his doctoral dissertation that he defended in 1951 at the Lebedev Physical Institute of the Academy of Sciences of the USSR.

During the last 15 years of his life, Malyuzhinets worked at the Acoustics Institute.

The contribution he made at that time to the development of approximate methods of the theory of diffraction cannot be overestimated. He applied the method of transverse diffusion to the problems of wave propagation in inhomogeneous media.

He gave special attention to the development of computational methods in the theory of diffraction. The fundamental results obtained by Georgy Danilovich Malyuzhinets on the wave propagation in inhomogeneous media served as the basis for the development of the methods and means of active noise and vibration control in shipbuilding and other areas of application.
