Cascading Disordered Resonant Metasurfaces: How to Assemble and Simulate
The visual appearance of nanoscale natural media always has been a paradigm in nanophotonics for achieving unique optical properties. Recently disordered manmade metasurfaces (MSs) allowed to harness specular and diffuse scattered light on-demand while preserving ultrathin and lightweight architectures. Thus, such unusual visual effects have been a step changer for innovative ultrathin coating technologies. We present here a method for fabrication and simulation of cascading disordered metasurface stacks. Off-plane electromagnetic coupling between MSs allows to manipulate separately specular reflection and diffuse light scattering from plasmonic nano-objects. We apply this unique functionality to realise large-scale diffuse light chromo-encryption. This work will guide material optimization for future innovative metasurface-based coating applications.
