Abstract: A switch matrix structure for planar circuitry such as printed circuit boards and integrated circuits includes a plurality of signal dividers and a plurality of switches. Each signal divider is configured to receive a corresponding input signal and generate a corresponding plurality of divider output signals. Each switch is configured to receive a corresponding divider output from a corresponding signal divider. Each switch is configured to provide a corresponding output signal such that a plurality of output signals are generated by the plurality of switches. In an example, the plurality of switches are arranged in a column, with a first subset of the plurality of signal dividers on a first side of the column, and a second subset of the plurality of signal dividers on a second side of the column. In an example, such a routing configuration reduces a number of routing layers and/or a number of via transitions.

Abstract: Integrated capacitor structures are described. In an example, an interconnect structure includes a first layer of conductive material and a second layer of conductive material. The first layer includes a first horizontal portion having a first opening and extending along a first horizontal plane, and a first vertical portion. The second layer includes a second horizontal portion having a second opening and extending along a second horizontal plane, and a second vertical portion. The interconnect structure also includes a dielectric extending along a third horizontal plane between the first and second horizontal portions, and having one or more openings. The first vertical component extends upward from the first horizontal portion, through one opening in the dielectric and the second opening of second layer, and the second vertical component extends downward from the second horizontal portion, through another opening in the dielectric and the first opening of first layer.

Abstract: Techniques are provided for jammer detection. A methodology implementing the techniques according to an embodiment includes steering a beam in a specified direction to generate a power measurement, the specified direction selected from a plurality of directions, such that the method comprises scanning through the plurality of directions. The method also includes adaptively steering a null in the specified direction and measuring a gain of the received signal in the null direction. The method further includes calculating a difference between the power measurement and the measured gain and generating a difference-based detection that the received signal is associated with a jammer at the specified direction. The difference-based detection is based on a comparison of the power difference to a power difference threshold value. The power difference threshold value is based on a desired probability of false alarm and probability of detection, and/or desired angular resolution.

Abstract: Techniques to dynamically adjust the corner frequency of a high-pass filter in response to a time-domain amplitude value of an output signal, thereby preserving accuracy while promptly recovering the signal's baseline value. A system can be configured to filter frequency-domain values of an input signal based on a filtering characteristic. The filtering characteristic can be set dynamically in response to a time-domain value of an amplitude of an output signal. The filtering characteristic can comprise a corner frequency, and the system can include a high-pass filter configured to filter out frequency components at frequencies lower than the corner frequency. The system is configured to dynamically change the corner frequency from a first value to a second value, in response to the time-domain value of the amplitude crossing a threshold value. The system may dynamically change the corner frequency within a time interval after the crossing.

Abstract: A panoramic Mid-Wavelength Infrared (MWIR) lens has a plurality of optical elements, wherein each optical element from the plurality of elements is formed from a material that transmits in at least the MWIR band from 3 μm to 5 μm. The plurality of optical element are arranged in a manner that provides a 360 degree azimuth angle and an elevation angle that is within +/−20° from a 90° horizon. The panoramic MWIR lens is configured to be connected to a cooled Dewar, wherein the Dewar includes a cold shield and an image plane to detect light in the MWIR band transmitted through the plurality of optical elements.

Abstract: A method includes forming a plurality of islands of first material on a plurality of first sections of a layer. A plurality of second sections of the layer are not covered by the first material. The method further includes depositing a second material on (i) the islands of first material and (ii) the second sections of the layer that are not covered by the islands of first material. The method further includes evaporating and/or sublimating the islands of first material and removing remnants of the second material that were on the islands of the first material. In an example, the second material remains on the second sections of the layer, to thereby form a pattern of the second material on the layer. In an example, the first material is a monomer, and the second material is a conductor or a dielectric or a semiconductor.

Abstract: A method of enhanced processing used to discriminate between ADS-B messages with a duplicate announced address comprising: receiving ADS-B messages that comprise information for display by a display of traffic information from at least two targets on a receiver; identifying the ADS-B messages having the duplicate announced address with one of the at least two targets using at least one discriminator by assigning a weighting factor to the at least one discriminator and, where the integration of the at least one discriminator and weighting factor exceeds a predetermined threshold value, considering the ADS-B messages that were subject to the at least one discriminator as being discriminated messages associated with one of the at least two targets; and displaying information provided by the discriminated messages on a display of traffic information as if the discriminated messages had been initially associated with only one of the at least two targets.

Abstract: A low profile, broadband radiator operates as a dielectric rod antenna (DRA) but is conformally mounted to a conducting sheet along its axis of symmetry. The new device exploits the imaging theory of electromagnetics to split the DRA in half while maintaining its full-height TEM feed, HE11 waveguide, and radiation taper characteristics. The disclosed device is attractive for applications requiring directed energy on or near the axis of the antenna, i.e. ‘end-fire’, and for high shock and velocity environments. Bandwidth extension is realized by adding one or more cores of higher dielectric material and by modifying the feed and mode formation regions. A second polarization is generated by configuring the feed for odd-mode transmission and creating a flared notch radiator within a metallized split launcher.

Abstract: A system and method are disclosed for a low F-number precision variable-focus telescope that includes a telescope housing containing an optical system. There is a first temperature sensing device to detect a temperature of the telescope housing, a second temperature sensing device to detect an ambient temperature around the telescope housing, and a pressure sensing device to detect ambient pressure around the telescope housing. A controller is in operative communication with the first temperature-sensing device, the second temperature sensing device, and the pressure sensing device. The control regulates the heater to maintain the telescope at a desired temperature to achieve diffraction limited performance in response to signals from the first temperature-sensing device, the second temperature sensing device, and the pressure sensing device.
