Optical metasurfaces based on plasmonic nanoparticles for anti-reflection coatings and transparent absorbers

摘要

In this contribution, we put forward an analytical model for the design of lossless and lossy nanoparticle-based metasurfaces working at a desired frequency in the optical spectrum. To show the versatility of our approach, we exploit it for the design of different innovative devices, such as cloaking-inspired anti-reflection coatings, circuit-analog screens and narrowband optical absorbers that are transparent outside their operation bandwidth. All the theoretical results are checked with full-wave simulations confirming the effectiveness of the analytical findings.
