The project theoretically and experimentally investigated various multilayer metamaterials, including Au/Al2O3 and Ag/Ti3O5 metal‐dielectric stacks with unique optical properties, symmetric Ag/SiO2 multilayers for spontaneous emission engineering, Cr/SiO2 multilayers for broadband absorption, and plasmonic perfect absorber metamaterials for structural color printing.
