On December 6, 2025, Anatolii Mykolaiovych Kondratenko — Distinguished Professor of V. N. Karazin Kharkiv National University, prominent plasma physics scholar, Doctor of Physical and Mathematical Sciences — celebrated his 90th birthday.

In 1958, Anatolii Kondratenko graduated with honors from the Nuclear Division of the School of Physics and Mathematics of Kharkiv State University (now the Education and Research Institute “School of Physics and Technology” of Karazin University). In 1971, he defended his doctoral thesis at the Ukrainian Physical and Technical Institute. In 1972, he joined the faculty of the School of Physics and Technology, where his scientific talent flourished, alongside his ability to recognize gifted students and engage them in fruitful research. From 1980 to 1990, he served as the Head of the Department of General and Applied Physics.

Thanks to his active and remarkably productive research career, Anatolii Kondratenko established a scientific school whose representatives continue to successfully develop multiple areas of plasma physics in many countries around the world. He has supervised and mentored 27 PhD candidates, seven of whom have successfully defended their doctoral dissertations. Despite the rapid advancement of plasma physics, his scientific results remain relevant today. He is the author of four monographs and more than 250 scientific publications, widely recognized by the international scientific community. His research has been distinguished with the K. D. Synelnykov Prize in Physics of the National Academy of Sciences of Ukraine.

Through decades of devoted work, Anatolii Mykolaiovych has achieved a number of outstanding results in the electrodynamics of bounded plasma, including:

• establishing the foundations of electrodynamics of plasma waveguides, including theories of propagation and damping of eigenmodes in various bounded plasma structures, wave transformation at plasma boundaries, excitation of eigenmodes by charged particle beams (including nonlinear beam–plasma interaction) and by external alternating electric fields, as well as the nonlinear theory of interaction between eigenmodes of bounded plasma structures;

• theoretical proof of the existence of surface ion-acoustic and cyclotron waves, as well as an entire class of electromagnetic perturbations capable of propagating along the plasma–metal interface;

• development of the foundations of plasma electronics, including theoretical models of excitation of plasma-filled waveguides and diffraction of eigenwaves in bounded plasma structures, along with theoretical justification for the operation of certain types of plasma-based electronic devices.

The Karazin community sincerely wishes Anatolii Mykolaiovych good health, family happiness, and many more wonderful years to come!
