Abstract
This paper describes the technology for manufacturing nichrome and chromium films on mica substrates by thermal vacuum deposition. The thickness of these films controlled by a resistive method, which ensures the production of films with a thickness of ~10 nm. Experimental results of the study of absorption of film structures of nichrome-mica, chromium-mica in the frequency range of 75–260 GHz on the installation consisting of a vector analyzer of electrical circuits R&SZVA-40 by Rohde&Schwarz with the measuring channels. The dependence of the absorption coefficient of nichrome and chromium films at the level of 0.5 in the frequency ranges 102–110 GHz, 206.6-223.6 GHz and 102-116,6 GHz, 206-226,6 GHz, respectively, is obtained. It is advisable to use films as a millimeter radiation absorber.
