  • Devices and Systems for Sensing and Locating Radio Frequency Signals
    Publication number: 20260160846
    Abstract: Embodiments are directed to methods and systems for sensing radio frequency (RF) signals. The system includes a quantum material film having an electrical resistance, and a source meter coupled to the quantum material film. The source meter is configured to: (i) measure the electrical resistance of the quantum material film, and (ii) output the measured electrical resistance of the quantum material film. A change in the output of the measured electrical resistance indicates a presence of an RF signal.

  • Time-varying metamaterial-enabled directional modulation for physical layer security in wireless communication links
    Patent number: 12555918
    Abstract: Various embodiments comprise systems, methods, architectures, mechanisms and apparatus providing secure physical layer (PHY) transmission via metamaterial (MTM) leaky-wave antennas (LWAs) using directed modulation (DM) transmitters such as for orthogonal frequency-division multiplexing (OFDM) and non-contiguous (NC) OFDM transmissions, where the DM functionalities exploit the property of time-modulated arrays (TMAs) realized in 1-D and 2-D spaces through the MTM-LWAs.

  • System and method for the delivery of information
    Publication number: 20020198958
    Abstract: A system and method for the delivery of information. A network permits the transfer of small to large data files through a variety of delivery methods, such as physical or electronic means. The information may include different types of media content, which may be selected and retrieved by a user. The user can select the location and time for delivery of the information, which is retrievable and downloadable to a personal device. This allows users to acquire the information in a relatively short period of time and at neighboring locations.
