Victor Yu Reshetnyak 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).

  • Dynamic optical and RF devices based on structured plasmonics and liquid crystal hybrids
    Patent number: 10481433
    Abstract: An optical/RF apparatus comprising a liquid crystal (LC) layer placed above or below a plasmon layer (e.g., a periodic array of graphene ribbons) to enable the tuning of the surface plasmons by varying the voltage applied to the LC to realize thereby devices such as tunable mid-IR, far-IR or THz modulators and filters.
    Type: Grant
    Filed: August 30, 2018
    Date of Patent: November 19, 2019
    Assignee: United States of America as represented by the Secretary of the Air Force
    Inventors: Victor Yu Reshetnyak, Dean R. Evans
  • Nanoparticle doped hybrid photorefractives
    Patent number: 9083149
    Abstract: The present invention provides a photorefractive hybrid cell including a window and a gain media disposed adjacent the window. The gain media includes nanoparticles therein. The window includes a material that forms a space-charge field. The gain media includes a material having refractive index properties that depend on an electric field. The nanoparticles include a coating which may include birefringent or polar molecules, other nanoparticles, organic material, or inorganic material.
