Patents by Inventor Maria Antonietta Vincenti

Maria Antonietta Vincenti 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).

  • Patent number: 10355348
    Abstract: An optically transparent graphene-based wire-grid polarizer for operating at microwave frequencies (X band) has a glass substrate having multiple strips or layers of SOCl2 doped graphene. The strips are separated by portions of the glass substrate such that the strips are arranged in parallel. The SOCl2 doped graphene strips have a quasi-metallic quality allowing for the transmission of an electric field with horizontal polarization in the horizontal direction while reflecting the vertical portion of the electric field.
    Type: Grant
    Filed: September 27, 2017
    Date of Patent: July 16, 2019
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Marco Grande, Giusseppe V Bianco, Maria Antonietta Vincenti, Domenico de Ceglia, Pio Capezzuto, Michael Scalora, Antonella D'Orazio, Giovanni Bruno

  • Patent number: 9768337
    Abstract: A photonic bandgap structure having multiple stacked layers has a thickness from the top of its top layer to the bottom of its bottom layer of less than one micron. Metal conducting layers having negative real dielectric constants are positioned between semiconductor layers having positive dielectric constants. The layers are arranged and stacked, and the thicknesses and materials for the semiconductor layers and conductive layers are selected to realize desired absorption, transmission, and reflection characteristics.

  • Patent number: 8993874
    Abstract: A photovoltaic cell having multiple stacked layers has a thickness from the top of its top layer to the bottom of its bottom layer of less than one micron. Metal conducting layers are positioned between semiconductor layers with semiconductor layers having higher bandgaps being located above semiconductor layers having lower band gaps. The layers of the photovoltaic cell are arranged and stacked, and the thicknesses and materials for the semiconductor layers and conductive layers are selected to realize desired absorption, transmission, and reflection characteristics. The geometry and thicknesses of the respective layers of the cell allows incident light of various angles to be absorbed by all of the semiconductor layers of the cell.
