Publication number: 20230017478Abstract: Methods and systems of eliminating corrupting influences caused by the propagation medium and the data capture devices themselves from useful image features or characteristics such as the degree of symmetry are disclosed. The method includes the steps of obtaining image-plane data using a plurality of data capture devices, wherein the image-plane data is a combined visibility from each of the data capture devices, measuring the closure phase geometrically in the image-plane directly from the image-plane, removing the corruptions from the image features based on the measured closure phase to remove the non-ideal nature of the measurement process, and outputting the uncorrupted morphological features of the target object in the image. The method relies on the Shape-Orientation-Size conservation principle for images produced from three visibilities made from a closed triad of data capture devices.Type: ApplicationFiled: July 9, 2021Publication date: January 19, 2023Applicant: Associated Universities, Inc.Inventors: Nithyanandan Thyagarajan, Christopher L.

Patent number: 10559885Abstract: A TEM line to double-ridged waveguide launcher and horn antenna are disclosed. The launcher uses multiple probes or one or more wide-aspect probes across the ridge gap to minimize spreading inductance and a TEM combiner or matching taper to match the impedance of the probes over a broad bandwidth. The horn uses a power-law scaling of gap height relative to the other dimensions of the horn's taper in order to provide a monotonic decrease of cutoff frequencies in all high-order modes. Both of these techniques permit the implementation of ultra-wideband designs at high frequencies where fabrication tolerances are most difficult to meet.Type: GrantFiled: January 24, 2019Date of Patent: February 11, 2020Assignee: Associated Universities, Inc.Inventor: Matthew Alexander Morgan

Patent number: 10530321Abstract: Reflectionless electronic filters, as well as a method for designing such filters is disclosed, along with a method of realizing critical subcircuits within those filters that mimic the behavior of tee- and pi-networks having negative elements, though the critical subcircuits themselves are entirely passive. This allows a much broader range of transmission responses to be realized in reflectionless form than in the prior art, and especially with lower ripple factor for deeper rejection in equal-ripple Chebyshev responses. Reflectionless filters preferably function by absorbing the stop-band portion of the spectrum rather than reflecting it back to the source, which has significant advantages in many different applications.Type: GrantFiled: April 2, 2019Date of Patent: January 7, 2020Assignee: Associated Universities, Inc.Inventor: Matthew A.

These filters preferably function by absorbing the stop-band portion of the spectrum rather than reflecting it back to the source, which has significant advantages in many different applications. The unmatched sub-networks preferably offer additional degrees of freedom by which element values can be assigned to realize improved cutoff sharpness, stop-band rejection, or other measures of performance.Type: GrantFiled: April 2, 2019Date of Patent: December 24, 2019Assignee: Associated Universities, Inc.Inventor: Matthew A.
