Abstract

The immense potential of metasurfaces is showcased by demonstrating several applications with plasmonic metasurfaces along with their polarization response using Mueller matrix spectroscopy. The work on plasmonic metalenses and holograms with an arbitrary composition of the AuAg alloys shows the successfully fabricated complex nanostructures only by heating nanostructures with a bilayer of Au and Ag of varying thickness at a low temperature of 300°C that retain the shape perfectly. In addition, the spin-orbit photonic effects in a waveguided plasmonic crystal after interacting with structured non-paraxial light via leaky mode excitation is imaged using dark-field Mueller matrix imaging.
