LYTVYNENKO LEONID MYKOLAYOVYCH

On the 7-th of May 2018, Leonid Mykolayovych Lytvynenko a prominent scientist in radiophysics and radioastronomy, Laureate of the State Prize of Ukraine in Science and Technology, Merited Worker in Science and Technology of Ukraine, Honored Professor of V. N. Karazin National University, Member of the NASU, Professor, Doctor in Phys. & Math., will celebrate his 80-th anniversary. In 1959, L. M. Lytvynenko graduated from A. M. Gorky University, specializing in radiophysics and electronics. He started his labor activity as an engineer at the “Electropribor” Special Design Office where he served from engineer to chief of research laboratory. In 1965, he finished his post-graduate study and defended his Ph.D. theses. In 1972, L. M. Lytvynenko upheld his thesis for a Doctor’s degree, and from 1977 he has been Professor in radiophysics.During 1966-69 period, he delivers lectures at Kharkov Institute of Radioelectronics. His further research and practical work is entirely connected with the National Academy of Sciences of Ukraine (NASU). Just with the NASU, he showed his brilliant talent of a scientist and an organizer of science.Professor Lytvynenko is one of the founders and a recognized leader of scientific school of theoretical radiophysics. He is also the founder of a new research school in the theory of diffraction and propagation in composite and multi-layer periodical structures. The suggested and developed concept of using the reflection operator by semi-infinite structures created the necessary prerequisites for developing fundamentally new quasi-optical elements and systems of millimeter and submillimeter wavelengths. Professor Lytvynenko places high emphasis on education and training of scientific manpower. For many years he delivers lectures for the students of radiophysical school at V. N. Karazin Kharkiv National University. He was scientific adviser of more than 20 Full Doctor and Ph.D theses. Many of his followers became leading teachers, scientists and famous specialists. Much of Professor Lytvynenko’s activity is dealt with management and administration. Thanks to his efforts, in 1980, the Department of Radioastronomy was organized with the Institute of Radiophysics and Electronics of NASU. Later in 1985, the Department was reorganized as Radio Astronomy Institute (IRA) NASU. Since then until 2017, Professor Lytvynenko has been Director of this Institute. IRA NASU carries out basic research in radioastronomy of the Universe, Geospace, and Solar system.
