  • Gyroid-based acoustic materials and devices
    Patent number: 12469479
    Abstract: An acoustic device includes a three-dimensional phononic crystal having cubic symmetry. The phononic crystal includes a first region filled with a first material and a second region filled with a solid material that is different from the first material. The second region is the solid complement of the first region. A boundary between the first and second regions is shaped as a single gyroid surface that has constant mean curvature and is not pinched off. The volume of the second region is greater than or equal to that of the first region. The first material may be a gas, such as air, or a fluid. The phononic crystal supports topological surface states, has a band structure with at least one degenerate point protected by nonsymmorphic symmetry, and exhibits negative refraction where two of its external surfaces meet.
    Type: Grant

  • High efficiency feed network for antennas
    Patent number: 6377227
    Abstract: A printed antenna comprising a dielectric substrate, dipole elements formed on a surface of the substrate, a matching network for coupling a driving point to the antenna elements, whereby common mode currents are minimized thereby minimizing the antenna performance degradation.
