Inspired by nature, a wide variety of "structural colors" have been artificially reproduced through the structuring of matter at the nanoscale. However, color is only one of many attributes of visual appearance. For example, gloss and translucency are just as important as color for our perception of objects. All these aspects have been neglected so far in the extensive literature on appearance design with nanostructured materials.
By combining concepts and tools from two very distinct disciplinary fields, nanophotonics and computer graphics, in order to initiate transverse collaborative actions in a newly created LP2N in 2011, LP2N researchers have developed a common numerical tool.
This tool, which combines electromagnetic simulation, multiple scattering model and image synthesis (BRDF), can predict the visual appearance of macroscopic nanostructured surface objects in realistic light environments, and has revealed that disordered metasurfaces made of nanoresonators can have impressive visual effects.
Their work has just been published in the journal Nature Material
