metasurfaces formed from plasmonic meta-atoms. In particular, we approach the subject from the perspective of the fundamental excitations supported by the meta-atoms and the interactions between them. We also identify some areas ripe for future research and indicate likely avenues for future device ...

Plasmonic metasurfaces are promising as enablers of nanoscale nonlinear optics and flat nonlinear optical components. Nonlinear optical responses of such metasurfaces are determined by the nonlinear optical properties of individual plasmonic meta-atoms. Unfortunately, no simple methods exist to determine the...

Demonstration of principle and method for metasuface designs (a) Schematic of the metasurface. The radius of each aperture is a = 1.75 μm, the spiral at which the apertures are located has a primary radius R0 = 12 μm, and the thickness of the gold film is h = 200 nm. The nanosli...
Keywords: metasurfaces; nonlinear optics; metamaterials 1 Introduction Metamaterials are a class of engineered materials comprised of meta-atom building blocks organized into arrays of subwavelength metal and/or dielectric components. Strong light-matter coupling in metamaterials produces novel linear and non...
metasurface proposed in this study introduces an air gap between the antennas and the surrounding media that confines the field within the gap,which mitigates the crosstalk between meta-atoms and minimizes metallic absorption.The proposed metasurface is broadband,versatile,easy to fabricate,and hig...
