What the paper is about?
The purpose of this work is to study of the optical properties of metasurfaces consisting of cylindrical metaatoms in the recently discovered hybrid anapole state. With the help of such metasurfaces, it was possible to obtain completely invisible metasurfaces based on new principles that is an alternative branch of development to the already known Huygens’ metasurfaces. This research might be helpful for the development of modern ultra-compact photonic devices based on new effects.
What are the results?
As a result, in this work, unique models of metasurfaces were developed, the meta-atoms of which are in the recently discovered hybrid anapole state. Such metasurfaces have full optical transparency, thereby competing with the already known Huygens’ metasurfaces while working on other principles. Such metasurfaces have many advantages, for example, the absence of interaction of meta-atoms with the substrate and with neighboring meta-atoms. Due to this, it becomes possible to choose practically any dielectric substrate for experiments, as well as the ability to create a disordered metasurface by varying the optical properties directly at the level of individual meta-atoms. Thus, all these features contribute to the development of the direction of creating different photonic devices based on hybrid anapole metasurfaces, for example, sensors, various lenses, holographic devices, and many more useful devices.
