Title: Angle multiplexed metasurfaces

Abstract

A metasurface is defined by an array of scattering elements having a U shape, where the geometrical dimensions determining the U shape are determined according to the different phase profiles that the metasurface is meant to generate in response to an incident electromagnetic wave. The metasurface, therefore, generates different phase shifts as a function of the incident electromagnetic wave.

High quality-factor fano metasurface comprising a single resonator unit cell

Patent Sinclair, Michael B.; Warne, Larry K.; Basilio, Lorena I.; ...

A new monolithic resonator metasurface design achieves ultra-high Q-factors while using only one resonator per unit cell. The metasurface relies on breaking the symmetry of otherwise highly symmetric resonators to induce intra-resonator mixing of bright and dark modes (rather than inter-resonator couplings), and is scalable from the near-infrared to radio frequencies and can be easily implemented in dielectric materials. The resulting high-quality-factor Fano metasurface can be used in many sensing, spectral filtering, and modulation applications.

Dispersionless and dispersion-controlled optical dielectric metasurfaces

Patent Arbabi, Ehsan; Arbabi, Amir; Kamali, Seyedeh Mahsa; ...

Metasurfaces comprise an array of pillars in a lattice. The dimensions of the pillars and the spacing are varied to obtain desired optical properties. The dispersionless metasurfaces can focus optical light over a broad wavelength range. Specific dispersion profiles for the metasurfaces can be designed. Gratings can be fabricated having similar properties as the array of pillars. Pillars in the metasurfaces can have different cross-section profiles.

Conformal optical metasurfaces

Patent Kamali, Seyedeh Mahsa; Arbabi, Ehsan; Arbabi, Amir; ...

Structures for scattering light at multiple wavelengths are disclosed. Scattering elements are fabricated with different geometric dimensions and arrangements, to scatter or focus light at the same focal distance for each wavelength, or at different focal distances according to the desired application. The scattering elements fabricated on a substrate can be peeled off with a polymer matrix and attached to a lens to modify the optical properties of the lens.

Metasurface skin cloak

Patent Ni, Xingjie; Wang, Yuan; Zhang, Xiang

This disclosure provides systems, methods, and devices related to a metasurface skin cloak. In one aspect, a metasurface skin cloak includes a dielectric layer and a plurality of blocks disposed on the dielectric layer. The dielectric layer is disposed over a surface including a feature on the surface. Each block of the plurality of blocks has a shape that is symmetric about two perpendicular axes. The metasurface skin can render the feature on the surface not optically detectable.

High quality factor non-uniform metasurfaces

Patent Barton, III, David Russell; Lawrence, Mark; Dionne, Jennifer A.; ...

High quality factor electromagnetic metasurfaces are provided. The metasurface is configured to have in plane guided-mode resonances (e.g., corresponding to waveguide modes or the like). Coupling features are included in the metasurface that are configured to couple free-space radiation to the guided mode resonances. The resulting structures have a high-Q response to free-space radiation and can be used for various applications, such as beam splitting, beam steering, and beam focusing or defocusing.
