    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: An optical detection apparatus includes a housing having a circumferential opening therein. A primary mirror reflects light rays to form a first set of light rays to a secondary mirror that has a generally concave shape coupled to the housing. A tertiary mirror having a generally concave shape coupled to the housing spaced apart from the secondary mirror directs light to detection optics that form an image using the third set of light rays. The detection optics include a micro-mirror array that redirect the image to a detector. A controller controls the micro-mirror array and determines an event characteristic based upon the image thereon.

Each belt includes a plurality of interconnected belt segments including a substrate having an electrically conductive digital data bus, and at least one module having a first sensor, a second sensor and a digital signal processor, and a coating for protecting the belt segment. The first and second sensors, which are preferably formed as microelectromechanical sensors sharing a common substrate, respectively generate signals representative of a first physical parameter and a second physical parameter. The processor receives and analyzes the first and second signals to generate a third signal. The third signal is transmitted along the electrically-conductive bus to a remotely-located controller. The controller analyzes the third signal to obtain flight status information relating to the effect of the physical parameters on the flight.

    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.
