摘要： A metamaterial comprises a substrate and a plurality of resonators supported by the substrate, each resonator including a first conducting segment and a second conducting segment, there being at least one adjustable capacitor and at least one bias capacitor located between the first and second conducting segments. In some examples, the first conducting segment, second conducting segment, bias capacitor, and adjustable capacitor are substantially coplanar and may be formed by patterning a metal film supported by the substrate. Bias lines may be configured so as to allow a bias potential to be applied between the first and second conducting segments so as to vary the capacitance of the adjustable capacitor.

摘要： A microwave lens having an array of electronic inductive capacitive cells wherein each cell includes an electrically conductive pattern which responds to incident microwave electromagnetic energy as an LC resonator. At least one of the cells includes at least one MEMS device which is movable in response to an electrical bias to thereby vary the resonant frequency of that cell. In order to bias the MEMS device, an electrical insulating layer extends along a portion of the pattern of the cell and to both sides of the MEMS device. An electrically conductive strip then extends over the insulating layer so that the conductive strip is electrically insulated from the pattern while electrically connected to the MEMS device.

摘要： An automotive radar system having a high frequency radio transmitter which generates a radar signal in a known direction. A high frequency radio receiver receives echoes from the radar signal in which each echo represents a reflection of the radar signal from an object. A processor then identifies animate objects, if any, from the received echoes within a range of interest and generates an alert signal for each such identified animate object.

摘要： A method and system for multiple microphone photoacoustic leak detection and localization. The leak detection technique uses photoacoustic sounds produced by the interaction of a carbon dioxide (CO2) laser turned to 10.6 microns and a photoactive tracer gas, sulfur hexafluoride (SF6), emitted by calibrated leak sources. As the leaked gas is heated by the laser, it expands and launches a photoacoustic sound pulse. The sound pulses generated by the scanning process are recorded across a broad bandwidth by multiple ultra-sensitive microphones. After the photoacoustic pulses arc recorded, the magnitude is compared with background noise measurement at several frequencies for a determination if a leak is present. If the presence of a leak is found, then the location of the leak is determined. The recorded sound is processed by using Matched Field Processing (MFP) as the signal processing technique. The photoacoustic sounds recorded at the microphones are reversed in time through computer simulation that causes the sounds to converge to the apparent point of origin. No synchronization between the acoustic signal processor and the laser scanner is required.
