This paper is dedicated to the 90-th anniversary of Vadym Borysovych Razskazovsky, an outstanding scientist in the fields of radio engineering and radio science, holder of the titles and positions like DSc (Engineering), Professor, and Head of the Statistical radio physics department at the O.Ya. Usikov Institute for Radio Physics and Electronics within the Academy of Sciences of Ukraine

Fizika və elektronika departamentinin müəllim və tələbələri Spin Coater və Sentrifuqa qurğuları hazırlamışlar

Spin Coaters and Centrifuges have been developed for the production of thin films for diodes and sensors as a result of the work of the faculty members of the Department Ahmad Azimov, Muhammad Alizade and Babak Emdadi in the laboratory "Electronics, Radio Engineering and Telecommunications" of the Physics and Electronics Department of Khazar University together with students

Introduction to physical acoustics

The book gives a concise account of physical acoustics – a branch of physics studying the interaction of acoustic waves with matter at the macro and microscopic levels. It starts with the basics of mechanics of continuum needed to analyse the problems of physical acoustics. This is followed by the description of linear and nonlinear problems of acoustics of gases, liquids and solids. Also considered are the problems of ‘turbulence and sound’, acoustics of magnetic media, and acoustics of crystals. Important information is provided also on acousto-electronics and acousto-optics. Some parts of the book are illustrated by description of the methodology of experiments and experimental data. The book would be of interest to undergraduate students of physical, chemical and engineering specialities, postgraduate students, researchers, lecturers, acoustic engineers, and all those engaged in fluid mechanics, elasticity, solid state physics, radio physics, signal processing, underwater acoustics and geophysics.

Interview with Roy W. Gould

Oral history interview in six sessions in 1996 with Roy W. Gould, Caltech Professor of Electrical Engineering, Physics and Applied Physics, 1955-1996 (emeritus 1996); Chairman, Division of Engineering and Applied Science, 1979-1985; and Caltech alumnus (BS, 1949; PhD, 1956). Gould describes his youth and student years at Caltech, beginning in 1944; Caltech during World War II and interruption of studies, resumption in 1946; courses in engineering and physics; BS in engineering. Graduate work begins at Stanford on microwaves with Lester Field; he returns to Caltech for a PhD in physics on microwaves and solar radio noise. Discusses microwave electronics community in the 1950s; J. Pierce, A. Haeff; recalls the "Tube Conferences." Job offers in industry but chooses Caltech, where he receives joint appointment in electrical engineering and physics. Recalls electrical engineering program at Caltech in the 1950s with C. Papas, G. McCann (analog computer), C. Wilts. Describes beginnings of his interest in plasma physics and thermonuclear fusion (late 1950s); connections with European plasma physics groups. Assumes directorship of Atomic Energy Commission [AEC] fusion program and moves to Washington; offered position of Deputy Science Advisor to President Nixon; returns instead to Caltech (1972). Builds tokamak at Caltech; fusion later becomes "Big Science." Birth of applied physics program at Caltech; its history. He discusses engineering division at Caltech; its diversity; his tenure as chairman. Recalls the rise of computer science and roles of C. Mead, I. Sutherland and C. Seitz. Comments on Caltech presidents, especially Goldberger and Everhart; changes in Caltech over the years. Epilogue 1998: on Gould's return to earliest interest, amateur radio

Seventy Years of Getting Transistorized

Vacuum tubes appeared at the break of the twentieth century giving birth to electronics. By the 1930s, they had become established as a mature technology, spreading into areas such as radio communications, long distance radiotelegraphy, radio broadcasting, telephone communication and switching, sound recording and playing, television, radar, and air navigation. During World War II, vacuum tubes were used in the first electronic computers, which were built in the United Kingdom and the United States. Although vacuum tubes had been a successful technology, they were also bulky, fragile and expensive, had a short life, and consumed a lot of power to heat the thermo-emitters. These drawbacks promoted the search for completely new devices. Alternative solutions had long been considered, but without significant developments
