Patents by Inventor Jeffrey L. Ruckman

Jeffrey L. Ruckman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Customizing the refractive index of a surface
    Patent number: 10983255
    Abstract: Mechanisms for customizing a refractive index of an optical component are disclosed. In one example, sub-wavelength openings are formed in a top layer of anti-reflective (AR) material of an optical component to tailor transmission characteristics of the AR material over a range of angles of incidence and a range of wavelengths. In another example, sub-wavelength openings are formed at different filling fractions in the surface of the optical component.
    Type: Grant
    Filed: December 8, 2016
    Date of Patent: April 20, 2021
    Assignees: Lockheed Martin Corporation, The Penn State Research Foundation
    Inventors: Clara R. Baleine, Corey L. Bungay, Theresa S. Mayer, Andrew Swisher, Jeffrey L. Ruckman, Stephen R. Tuenge
