  • Patent number: 10038230
    Abstract: Arrangement of resonators in an aperiodic configurations are described, which can be used for electromagnetic cloaking of objects. The overall assembly of resonators, as structures, do not all repeat periodically and at least some of the resonators are spaced such that their phase centers are separated by more than a wavelength. The arrangements can include resonators of several different sizes and/or geometries arranged so that each size or geometry corresponds to a moderate or high “Q” response that resonates within a specific frequency range, and that arrangement within that specific grouping of akin elements is periodic in the overall structure. The relative spacing and arrangement of groupings can be defined by self similarity and origin symmetry.

  • Patent number: 10030917
    Abstract: Systems according to the present disclosure provide one or more surfaces that function as heat or power radiating surfaces for which at least a portion of the radiating surface includes or is composed of “fractal cells” placed sufficiently closed close together to one another so that a surface (plasmonic) wave causes near replication of current present in one fractal cell in an adjacent fractal cell. A fractal of such a fractal cell can be of any suitable fractal shape and may have two or more iterations. The fractal cells may lie on a flat or curved sheet or layer and be composed in layers for wide bandwidth or multibandwidth transmission. The area of a surface and its number of fractals determines the gain relative to a single fractal cell. The boundary edges of the surface may be terminated resistively so as to not degrade the cell performance at the edges.

Further described are boundary condition layer structures that can activate and deactivate cloaking/lensing structures.

  • Patent number: 10014586
    Abstract: Aspect of the present disclosure are directed to methods and apparatus producing enhanced radiation characteristics, e.g., wideband behavior, in or for antennas and related components by providing concentric sleeves, with air or dielectric material as a spacer, where the sleeves include one or more conductive layers, at least a portion of which includes fractal resonators closely spaced, in terms of wavelength. A further aspect of the present disclosure is directed to surfaces that include dual-use or multiple-use apertures. Such aperture engine surfaces can include a top (or first) layer of antenna arrays, a middle (or second) layer of a metal-fractal backplane player, and a third (or bottom) layer for solar cell or solar oriented power collection.

  • Patent number: 10006747
    Abstract: Systems and methods for drone mitigation, or the deterrence of aerial drones from flying in an given area, are described. The systems and methods take advantage of the fact that destabilization of a drone can be accomplished by externally changing the performance of one or more of its propeller driven systems. In doing so, the drone is incapable of maintaining stability in flight, thereby causing the remote controlled pilot to force a retreat, or risk and result in a crash of the drone. Embodiments utilizing sonic energy and liquids are described.

  • Publication number: 20180157875
    Abstract: Plasmonic-surface antenna systems are described in which resonators, or cells, are closely arranged but do not touch. At least a portion of a radiating surface includes a plurality of cells (operative as resonators) placed very close together to one so that a surface (plasmonic) wave causes near replication of the current of one cell in an adjacent cell. Cells with one or more fractal shapes may be used as a fractal plasmonic surface (FPS). Systems and/or methods are described of using plasmonic surfaces or fractal plasmonic surfaces for radiofrequency identification (RFID). A PS or FPS may act as an intermediary array of antennas, which can serve to connect an RFID reader with one or more RFID tags. Structures including cages are described that can include one or more surfaces that are each an FPS. Methods of power transfer are described.

  • Publication number: 20180114989
    Abstract: An aspect of the subject technology/invention of the present disclosure includes electrode structures or elements/components that have (e.g., present) fractal and/or self-complementary shapes or structures, e.g., on a surface. Such shapes or structures can be pre-existing. The electrodes can be made of any suitable material. The electrodes may function or operate or be used as a “seed” structure to incorporate or receive a material or materials useful for lattice assisted nuclear reactions and/or cold fusion processes.

  • Publication number: 20180040958
    Abstract: Cage antennas and related components are described. Such cage antennas include a shortened antennal element, such as a monopole (e.g., of approximately ?-wave height of a desired operational wavelength), which can be placed on a shortened ground plane (e.g., roughly quarter-wave size). A cage-like ensemble (e.g., a cage) can then be placed on top of but not touching the antenna element. The cage structure can have a fractal-based, folded, and/or pleated structure, among others. This cage structure can be produced either through a variety of means including but not limited to 3-D printing with either conductive materials or inductively coded materials.
