  • Patent number: 11914266
    Abstract: In various embodiments, a tunable optical surface includes a dielectric substrate layer with an array of elongated metal rails extending from the dielectric substrate parallel to one another and spaced from one another to form channels therebetween. The channels are etched deeper into the dielectric substrate to form extended-depth channels. The depth of each extended-depth channel is greater than the height of adjacent elongated metal rails. The dimensions of the elongated metal rails and the extended-depth channels therebetween may be subwavelength with respect to an operational bandwidth. A tunable dielectric material that has a tunable refractive index, such as liquid crystal, is positioned within the extended-depth channels between adjacent elongated metal rails.
