Click here to see what’s new. Integrated Photonics Research, Silicon and Nanophotonics Remember me on this computer. There has been a growing amount of attention to 2D metasurfaces since their introduction for manipulating the propagation of electromagnetic waves.
Negative Refraction and Light Bending with Plasmonic Nanoantennas
Equations displayed with MathJax. Although our design consists of ligth separated layers, this fabrication process is arguably simpler than for single-layer metasurfaces.

We marry these two metasurfaces together to form a bilayer metasurface. He, High-efficiency broadband anomalous reflection by gradient meta-surfaces, Nano Lett. The entire structure is ultrathin, with a thickness of nm about a sixth of the wavelength.
Remember me on this computer. In summary, we have designed and experimentally demonstrated a new metasurface configuration.
Our findings show plzsmonic the generalized Snell’s law still applies in the presence of such strong mutual coupling.

In addition to providing all the benefits of plasmonic metasurfaces in terms of light manipulation with our hybrid bilayer metasurface, we also overthrow the theoretical efficiency upper limit of ultrathin plasmonic metasurfaces. To design the geometry for a given wavelength, we therefore tailor the parameters of all subunit cells as a whole by considering the coupling of all neighboring elements.

We exploit both this intra-layer and inter-layer coupling to enhance the overall manipulation efficiency. Height of bening HSQ pillars. Efficient manipulation of visible light is achieved with a V-shaped bilayer metasurface.
