Alessandro Salandrino 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: 9008471
    Abstract: Circuits and circuit elements adapted to function at optical or infrared frequencies are made from plasmonic and/or nonplasmonic particles disposed on a substrate, where the plasmonic and nonplasmonic particles have respective dimensions substantially smaller than a wavelength of an applied optical or infrared signal. Such particles are deposited on a substrate in a variety of shapes and sizes from a variety of plasmonic and/or nonplasmonic materials so as to form resistors, capacitors, inductors and circuits made from combinations of these elements.
    Type: Grant
    Filed: June 20, 2005
    Date of Patent: April 14, 2015
    Assignee: The Trustees Of The University Of Pennsylvania
    Inventors: Nader Engheta, Alessandro Salandrino, Andrea Alu
  • Patent number: 8254227
    Abstract: A frequency-modulated coding and data recording and storage device that uses plasmonic-dielectric nanostructures of concentric two-layer core-shell design to store data includes a flat transparent substrate having a top surface divided into cells with side dimension d on the order of tens of nanometers and a core-shell plasmonic-dielectric nanostructure disposed in each cell. Each plasmonic nanostructure of concentric core-shell has a predetermined ratio of radii and a predetermined aspect ratio such that when an infrared or visible wavelength signal is applied to each said core-shell plasmonic-dielectric nanostructure a peak scattering amplitude of the applied signal is at different plasmonic resonance frequencies for core-shell plasmonic-dielectric nanostructures with different ratio of radii and different aspect ratios.

  • Patent number: 8116009
    Abstract: Far-field sub-diffraction optical lenses “FaSDOLs” comprise an anisotropic crystal having special dispersion characteristics such that it supports diffraction free propagation. An image with subwavelength features on the input surface is transferred through a propagation function to the output surface with effectively no, or minimal, loss in information. These special properties may be exploited in several ways, including but not limited to, magnification of an image at the input surface through the use an oblique cut at the output surface, magnification of an image at the input surface through use of a curved crystalline structure, and more generally near-field optical processing.
