Abstract: A metamaterial control device is provided for controlling electromagnetic radiation. The device uses a light-guide film (LGF), with the LGF being capable of receiving light emission along an edge. The device includes a substrate disposed on a non-edges surface of the LGF, electromagnetic cellular structures that are controllable, and an optically sensitive component within some or all cells. The substrate is composed of metamaterial and having an interface that corresponds to an extractor on the non-edge surface for scattering light therefrom. Alternatively, the substrate can constitute the LGF itself. The cell structure is disposed around the extractor. The optically sensitive component is disposed to cover the extractor. The component changes in response to receiving the light from the extractor and changes in response to intensity of the light.

Abstract: A material is provided for switching dielectric constant between distinct first and second values responsive to electromagnetic radiation having a specified energy. The material includes a medium transparent to the radiation and a plurality of particulates. Each particulate has a dipole that assumes one of distinct first and second parameters that correspond to the first and second values. The particulates are suspended within the medium. The parameters are either dipole span or charge strength. The dipole of each particulate sets to the first parameter by default and sets to the second parameter in response to the radiation. The particulates can be composed from undoped semi-insulating gallium arsenide. The medium can be polymethylmethacrylate, for example.

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.

Furthermore, the invention relates to the use of these peptides conjugated or fused to other peptides and chemical compounds which penetrates into cells as well as with the use of both peptide and chemical mimetic molecules.

Abstract: A dynamically variable lens is made from actively tunable electromagnetic metamaterial cells. The lens operates on electromagnetic radiation including: radio frequency waves, microwaves, teraherz waves, near infrared waves, infrared waves and visible waves. The focal length of the lens is changed at a selected frequency. In the alternative, the frequency of radiation operated on is changed as a function of time. A third alternative provides precise control of the index of refraction of the lens. The index of refraction is varied progressively across the lens from one edge to the opposite edge causing the radiation to be directed at an angle.

Abstract: The present invention deals with recombinant polypeptide molecules related to antibodies, that specifically recognize the human Vascular Endothelial Growth Factor A (VEGF-A), and interfere with its in vitro stimulatory effects and pro-angiogenic activity in vivo. These recombinant polypeptide molecules affect proliferation of human endothelial cells in vitro, subcutaneous angiogenesis in mice induced by Matrigel pellets that contain VEGF-A and the growth of human tumors transplanted in nude athymic mice. Several of these moleculas prevent choroideal neovascularization in a non human primate experimental model.
