Abstract
Chiral thin film structures based on arrays of cobalt nanohelices obtained by oblique angle deposition were experimentally studied. It was shown that, in the conditions of electron-beam evaporation on rotating inclined substrate, arrays of nanohelices wound in the same direction are formed. By varying substrate rotation speed, it is possible to change geometrical sizes of those helixes (helix pitch, helix radius). The thus obtained chiral metasurface demonstrates pronounced asymmetry of optical characteristics at the reflection of right and left circular polarized light.
期刊介绍：
Bulletin of the Russian Academy of Sciences: Physics is an international peer reviewed journal published with the participation of the Russian Academy of Sciences. It presents full-text articles (regular, letters to the editor, reviews) with the most recent results in miscellaneous fields of physics and astronomy: nuclear physics, cosmic rays, condensed matter physics, plasma physics, optics and photonics, nanotechnologies, solar and astrophysics, physical applications in material sciences, life sciences, etc. Bulletin of the Russian Academy of Sciences: Physics focuses on the most relevant multidisciplinary topics in natural sciences, both fundamental and applied. Manuscripts can be submitted in Russian and English languages and are subject to peer review. Accepted articles are usually combined in thematic issues on certain topics according to the journal editorial policy. Authors featured in the journal represent renowned scientific laboratories and institutes from different countries, including large international collaborations. There are globally recognized researchers among the authors: Nobel laureates and recipients of other awards, and members of national academies of sciences and international scientific societies.
