摘要： A leaky cavity resonator that includes a waveguide, the waveguide being filled with a dielectric material, and at least two complementary split ring resonators (CSRRs), the CSRRs residing inside the waveguide parallel to each other placed symmetrically both radially and in height, a leaky resonant cavity being formed between the at least two CSRRs and a wall of the waveguide. A frequency band of the leaky cavity resonator is adjustable by varying a distance w between at least one outside perimeter of at least one CSRR and an interior wall of the waveguide. A frequency band of the leaky cavity resonator is also adjustable by varying a size of the leaky resonant cavity. The at least two CSRRs each have at least one stub connecting to a wall of the waveguide. A frequency band of the leaky cavity resonator is also adjustable by varying a size of the stubs.

摘要： 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.

摘要： 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.

摘要： An ultraviolet laser generates a coherent beam, which is downconverted to produce pairs of frequency-entangled photons. For each entangled pair, a first photon is sent along a first path and a second photon is sent along a second path. A first detector detects those photons sent along the first path, and a second detector detects those photons sent along the second path. The detection is performed in a single photon regime. Coincidence counting is performed on outputs of the detectors, including comparing leading edges on outputs of the first and second detectors within a time window.

摘要： Integrated laser head apparatus is disclosed for producing high energy pulses in pulsed gas lasers. The present invention provides high energy pulses over short time durations suitable for laser rangefinder systems due to an improvement in the arrangement of energy storage capacitors (22, 24) which keeps circuit inductance to a minimum. The pair of nested, ceramic capacitors (22, 24) are substantially cylindrical and are coupled through thin conductive layers (23). The capacitors are charged by a spark gap trigger (14), an inductor (18), and a charging resistor (52). The capacitors (22, 24) enclose a pressure vessel (28) which further encloses a laser resonator (12) including a laser output coupler mirror (42), totally reflective mirror (44), discharge electrodes (32, 34) and a central chamber (30) which contains a pressurized gaseous phase laser medium. The high voltage discharge electrode (32) is disposed coaxially with the surrounding capacitors (22, 24).

摘要： 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.
