    摘要： This disclosure provides systems, methods, and apparatus related to nanophotonics. In one aspect, an arrangement of waveguides includes a substrate and three waveguides. Each of the three waveguides may be a linear waveguide. A second waveguide is positioned between a first waveguide and a third waveguide. The dimensions and positions of the first, the second, and the third waveguides are specified to substantially eliminate coupling between the first waveguide and the third waveguide over a distance of about 1 millimeter to 2 millimeters along lengths of the first waveguide, the second waveguide, and the third waveguide.

    摘要： 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.
