Abstract: A light transmission system is provided for operating an optically responsive circuit. The system includes a light guide film (LGF) to transmit light emitted from its edge, and a scattering node for directing the light to the circuit. The circuit is disposed on a proximate face of the LGF. The scattering node is disposed on a distal face of the LGF opposite the circuit. The circuit can be an integrated circuit, a light detection sensor or a photovoltaic cell.

Abstract: A radio frequency identifier (RFID) tag is provided for receiving and reflecting electromagnetic energy at select frequency bands of visible and infrared wavelengths. The RFID tag includes an electrically conductive backplane; a dielectric substrate disposed on the backplane; a light guide film (LGF) disposed on the substrate, and metamaterial elements. The LGF has an exposed surface segregated into domains. The metamaterial devices are disposed on a domain. Each device is tuned to respond to a corresponding frequency among the select frequency bands.

Abstract: An electromagnetic reflector for reflecting an electromagnetic signal is provided based on meta-surface phase control using photo-capacitive materials, varactors or other tuning means. The shape of the metamaterial unit cell enhances the resonance and phase shift. The reflector includes first and second cells having respective first and second phase states, along with a switch for selecting between the first and second cells.

Abstract: A photocapacitor device is provided for responding to a photon having at least a specified energy. The photocapacitive device includes a first portion composed of a photocapacitive material; a second portion composed of a non-photocapacitive material; and a depletion region disposed between the first and second portions. The photocapacitive and non-photocapacitive materials respectively have first and second Fermi-energy differences, with the second Fermi-energy difference being higher than the first Fermi-energy difference.

Abstract: A micro designator dart engages a target to allow for designation and tracking of the target by transmitting a radio-frequency identification code. The housing of the micro designator dart is configured to enclose its components and deform upon impact with a target to allow a target-engaging member to physically attach the micro designator dart to the target. Also upon impact with the target, an impact-sensitive triggering mechanism in the micro designator dart activates a power source, causing a transmitter to send a predetermined coded infrared signal to the seeker unit of a precision guided munitions system. The micro designator dart may also include a self-destruct device.

Abstract: A detector is provided for sampling and identifying a material, such as a medium in which the detector is disposed. The detector includes an annular photonic crystal fiber, first and second electrodes, an electrical power supply, an illumination source and an analyzer. The fiber has opposite longitudinal ends, surrounds a center core tube and includes fused capillary tubes. The electrodes are disposed between the fiber's longitudinal ends. The electrical power supply connects between the electrodes. The illumination source emits light into the core tube from one of the opposite ends. The analyzer for compares an emission pattern from light transverse to the fiber against an established pattern, and indicates match in response to correspondence between the patterns. The annular structure has a two-dimensional optical photonic band-gap. The analyzer monitors the emission pattern by optical frequency domain reflectometry or optical time domain reflectometry.

Abstract: Carbon nanotube apparatus, and methods of carbon nanotube modification, include carbon nanotubes having locally modified properties with the positioning of the modifications being controlled. More specifically, the positioning of nanotubes on a substrate with a deposited substance, and partially vaporizing part of the deposited substance etches the nanotubes. The modifications of the carbon nanotubes determine the electrical properties of the apparatus and applications such as a transistor or Shockley diode. Other applications of the above mentioned apparatus include a nanolaboratory that assists in study of merged quantum states between nanosystems and a macroscopic host system.

Abstract: The present invention provides a power frequency, i.e., time-varying, magnetic field (PF-NF) detector system for characterizing the operational condition of a remote facility responsive to time-varying magnetic fields generated by electrical transmission lines associated with the remote facility. The PF-MF detector system advantageously includes a PF-MF sensor which generates N time-varying magnetic field data sets, and a PF-MF analyzer which generates an operational condition assessment responsive to the N time-varying magnetic field data sets, wherein N is an integer greater than or equal to 1. Additionally, the PF-MF detector system includes an accumulator which stores and forwards the N time-varying magnetic field data sets to the PF-MF analyzer via a communications channel. A method for characterizing the operational condition of inaccessible electrical equipment responsive to the time-varying magnetic field generated by a transmission line are also described.
