International Classification:

G01S 13/00

US Classification:

342 22, 324330

Abstract:

A system or method of creating a map of voids in the ground based on a scattered electromagnetic signal includes traversing a receiver/probe in a near field above a target area; generating a signal from a signal transmitter, the signal having a predetermined wavelength λ; receiving a scattered signal with the receiver/probe, the scattered signal including indications of subsurface variations via reflection of the generated signal; and detecting evanescent components of the scattered signal to provide a predetermined resolution. The method includes the use of an electrically small antenna for resolution of subwavelength features. The metamaterial-based antenna is on the order of meters and has an efficient transmit/receive capability. The ESA is 1/10 of the length of the equivalent dipole length, and may be scaled down to 1/10,000. Such an antenna may include phase sensitive current injection in the metamaterial resonant structures for loss-compensation.

International Classification:

H01Q 15/02

US Classification:

343909, 343872

Abstract:

A method and apparatus for a negative index metamaterial lens. The method is used for creating a negative index metamaterial lens for use with a phased array antenna. A design is created for the negative index materials lens that is capable of bending a beam generated by the phased array antenna to around 90 degrees from a vertical orientation to form an initial design. The initial design is modified to include discrete components to form a discrete design. Materials are selected for the discrete components. Negative index metamaterial unit cells are designed for the discrete components to form designed negative index metamaterial unit cells. The designed negative index metamaterial unit cells are fabricated to form fabricated designed negative index metamaterial unit cells. The negative index metamaterial lens is formed from the designed negative index metamaterial unit cells.

International Classification:

G01S 13/00

US Classification:

342179, 342175

Abstract:

A system, apparatus, and method are disclosed for a super-resolution imaging radar (SRIR). The SRIR employs a pulse signal generator that propagates bursts of radio frequency (RF) energy. Each burst contains a number of pulses. One pulse of each burst is an ancilla pulse, and the remaining pulses are propagated towards an object. An array bucket detector (ABD) collects pulses that are reflected from the object. Also, the ancilla pulses are propagated through a virtual lens. A virtual scanning detector detects the virtual ancilla electric field. A processor calculates a virtual ancilla electric field, which would be present at the scanning detector. Further, a coincidence circuit calculates a cross-time correlation function of the electric fields of the reflected pulses that are collected by the ABD and the virtual ancilla electric field. The coincidence circuit uses cross-time correlation function results to generate pixels of an image of the object.

Abstract:

A system, method, and apparatus for a super resolution radar image extraction procedure are disclosed. The super-resolution imaging radar (SRIR) system involves a pulse signal generator, an array bucket detector, an ancilla beam detector, and a coincidence circuit. The pulse signal generator propagates N number of bursts of radio frequency (RF) energy, where each burst contains M number of dithered pulses. The pulses are propagated towards an object of interest and the ancilla beam detector. The array bucket detector collects pulses that are reflected from the object. The ancilla beam detector scans in a direction of the dithered pulses, and collects the dithered pulses. The coincidence circuit calculates a cross-time correlation function from the pulses that are collected by the array bucket detector and the ancilla beam detector. The coincidence circuit sums cross-time correlation function results to generate pixels of an image of the object.

International Classification:

US Classification:

244130, 244200, 244205, 4286921, 4286931

Abstract:

A metamaterial has a magnetic permeability response at frequencies sufficient to generate a repulsive force between a fluid and a surface to which the metamaterial may be applied. The metamaterial may be nanofabricated such that an absolute value of the magnetic permeability of the metamaterial is substantially greater than an absolute value of an electric permittivity of the metamaterial. The metamaterial may generate a repulsive force between the surface and the fluid moving relative to the surface and thereby reduce viscous drag of the fluid on the surface. A method of reducing the viscous drag of the fluid moving past the surface includes producing relative motion between the surface and the fluid and generating the repulsive force between the surface and the fluid.

International Classification:

US Classification:

356484

Abstract:

An object that might be at least partially obscured is imaged. Frequency-entangled photons are generated. The frequency-entangled photons include photons having first and second frequencies. Those photons having the first frequency can pass through the obscuration and illuminate the object. Photons scattered by the object and those photons having the second frequency are used to form an image by considering coincidences in time of arrival.
