  • Patent number: 11556683
    Abstract: A method and system for modeling fibrous composites. Initially, material properties are obtained for a model of a fibrous composite, where the model includes integration points and unit cells. For each integration point, composite level stresses and strains are determined based on the material properties, the composite level stresses and strains are decomposed into component level stresses and strains for the integration point, the component level stresses and strains are used to calculate failure quotients at the integration point, an appropriate material reduction model is applied at a component level based on the failure quotients to detect a component failure, the component failure is upscaled to determine updated material properties at a composite level, and the updated material properties are incorporated into the model. At this stage, a composite failure is detected based on the updated model.

  • Patent number: 11532478
    Abstract: A method for activating implanted dopants and repairing damage to dopant-implanted GaN to form n-type or p-type GaN. A GaN substrate is implanted with n- or p-type ions and is subjected to a high-temperature anneal to activate the implanted dopants and to produce planar n- or p-type doped areas within the GaN having an activated dopant concentration of about 1018-1022 cm?3. An initial annealing at a temperature at which the GaN is stable at a predetermined process temperature for a predetermined time can be conducted before the high-temperature anneal. A thermally stable cap can be applied to the GaN substrate to suppress nitrogen evolution from the GaN surface during the high-temperature annealing step. The high-temperature annealing can be conducted under N2 pressure to increase the stability of the GaN. The annealing can be conducted using laser annealing or rapid thermal annealing (RTA).

  • Publication number: 20220390553
    Abstract: A method for generating ultrawideband pulsed microwave signals from optical field ionization of a gas with an ultrashort laser pulse, where the amplitude and frequency of the signals can be controlled via the characteristics of the laser pulse and/or the gas. The center frequency of the spectrum of the microwave signal can be controlled by changing the laser pulse energy. The amplitude of the microwave signal can be controlled by changing the wavelength of the laser pulses. The amplitude and frequency of the microwave signal can be tuned by controlling the pressure of the gas medium. The location at which the microwave signal is generated can be controlled by controlling the location at which the laser pulse creates a plasma. Interference among microwave signals resulting from multiple laser-produced plasmas can be used to construct an ultrawideband microwave signal having a predetermined amplitude and frequency.

  • Publication number: 20220375034
    Abstract: A method for using a single-pixel camera to reconstruct images of objects obscured by fog or other dynamic scattering media. A pseudo-random phase or intensity pattern is imposed on illumination beams directed at a target. The beam with the imposed pattern forms a pseudo random pattern on the target. Information regarding the pattern imposed on each pulse is entered into a data processor/controller. The illumination beams with the pseudo random patterns are reflected off the target, collected by receiving optics and a bucket detector and converted into electronic signals fed into the data processor/controller. The data processor/controller applies a high-pass filter to remove slower signal variations produced by dynamic changes in the scattering medium over time. The filtered bucket values are then used together with their corresponding speckle patterns to generate the images using any appropriate reconstruction algorithm such as CGI or CSI.
