Rapid progress in the development of metasurfaces allowed to replace bulky optical assemblies with thin nanostructured films, often called metasurfaces, opening a broad range novel and superior applications generation, manipulation, detection light classical optics. Recently, these developments started making headway quantum photonics, where opportunities arose for control nonclassical nature l...

Abstract Topological photonics seeks to control the behaviour of light through design protected topological modes in photonic structures. While this approach originated from studying electrons solid-state materials, it has since blossomed into a field that is at very forefront search for new types matter. This can have real implications future technologies by harnessing robustness applications ...

Structuring metallic surfaces allows for the support of surface electromagnetic modes at frequencies which they would not be allowed smooth surfaces. These are called ``spoof plasmons'' because their similarity to plasmons that supported optical This article describes physics underlies behavior spoof and how these used in applications require manipulation fields below optical.
