Latest Patents

Among his latest inventions is the groundbreaking "Out-of-plane computer-generated multicolor waveguide holography." This patent describes various examples of multicolor waveguide holography systems, methods of manufacture, and methods of use. The system features a planar waveguide that conveys optical radiation between a grating coupler and a metasurface hologram. It is uniquely designed to couple out-of-plane optical radiation of three different colors incident at three distinct angles into the planar waveguide. The metasurface hologram then diffractively decouples these colors for off-plane propagation, creating a multicolor holographic image in free space.

Another notable patent by Smith is for a "High temperature superconductor." This invention involves a superconductor device that boasts an enhanced superconductivity transition temperature. It accomplishes this through a combination of a matrix material and a core material, which together create a system of strongly coupled carriers. The innovative elements of the design—such as low-dimensional conductive features embedded in the matrix—enhance the superconducting properties of the device.
