60 years from creation of Radiophysics and electronics department in Sofia University were completed in 2005. The department is established in 1945 under the name “Applied physics” in the Faculty of physics and mathematics with a goal to educate young physicists in the field of radiophysics and electronics. Emil Djakov was elected extraordinary professor and became head of the department. The new department was a branch of the Experimental physics department. The head of Experimental physics department – Professor G. Nadjakov – made the initial form of new department and Professor E. Djakov took great pains to form its education and science performances.
Professor Djakov's research moderateed during his specialization in Berlin (Germany) in 1936/37. He developed new methods for measurement the UHF-resistances. After his return in Bulgaria in 1939, he was elected for assistant professor and created the courses of applied physics and physical base of electrical engineering. He worked in physics and technics magnetrons. His scientific results have found a wide interest among the scientific comunity in foreign countries. In 1949, the department of Applied physics was renamed in Technical physics.
In this report the development of department from 1951 up to our days is being tracked. The decade between 1951 and 1960 marks beginning of organized science work in the department. Its experimental base was upgraded endlessly due to the efforts of the assistants K. Stamenov and T. Stoychev. Professor E. Djakov wrote two authorial textbooks for the course of electrical engineering and electronics . That fact represents an exception about the years, when Bulgarian textbooks, exploited in the Faculty of physics could be counted on the fingers of one’s hand. We used as well guidebook for laboratory written from K. Stamenov and T. Stoychev.
The decade from 1961 to 1970 was qualified with regular changes to lecturer constitution in the department and made an expansion in the area of science surveys.
The decade from 1971 to 1980 is called “swarming” in the department because a growth of scientific area and tasks. That is most major in the area of quantum electronics. In 1974, department of technical physics is renamed in Radiophysics and electronics. In 1978, the group of quantum electronics became self-depended department. With the unexpected death of Professor Djakov in the same year the university physicists and physicists from Bulgarian Academy of Science lose dear frend and famoust scientist.
After the Second World War Bulgarian physics overgrow in pregnant and institutional plan. This is the time when the administrative heads as a Professor E. Djakov show their ability and tolerance to the variety from science surveys, contribute to the Bulgarian physics and the training of physicist generation. Members from the Radiophysics and electronics department will remember the name of Professor Emil Djakov as a founder of academic department and institutions in Bulgarian academy of science with which the department members support many year good professional contacts. The development of our department in the following decades (tracks in the report) became possible due to the solid base situated just from Professor Emil Djakov.
