“…At that time his research interests shifted to the application of HDB technology in several promising civilian and defense-oriented areas such as materials testing and radar-cross-section measurements of the downscaled models of sea-borne and air-borne targets [19]. Still the sum-millimeter wave diagnostics of hot plasma inside IAE's nuclear fusion machines was the most important area of application, which culminated into the 0.195-mm wavelength nine-channel interferometer-polarimeter system installed at Tokamak-15 [7,3]. When Ukraine became independent nation in 1992, the smoke of secrecy around microwave research started getting taken away by fresh winds.…”
