Patent number: 11916291Abstract: According to various embodiments, systems and methods for spatial sampling in proximity to the Nyquist limit in traveling-wave antenna systems are disclosed. An apparatus can include a traveling-wave antenna array comprising a plurality of adjacent traveling-wave antennas that each include a plurality of tunable elements that are spaced at, near, or above a Nyquist limit spacing to form an array of tunable elements. The apparatus also includes a phase diversity feed coupled to the traveling-wave antenna array that is configured to provide input to the traveling-wave antenna array including phase diverse input to two or more of the plurality of adjacent traveling-wave antennas. Further, the apparatus includes a plurality of grayscale tuning elements configured to tune the plurality of tunable elements along one or more ranges of one or more tuning variables to form one or more specific output radiation patterns through the traveling-wave antenna array based on the input.Type: GrantFiled: June 6, 2023Date of Patent: February 27, 2024Assignee: Duke UniversityInventors: Michael Boyarsky, Timothy Sleasman, Jonah Gollub, Seyedmohammadreza Faghih Imani, David R.

Patent number: 11598866Abstract: A single frequency, or very narrow frequency band, microwave imaging system is described herein. A microwave imaging system can include an array transmitter; an array receiver; and a computing device that receives signals detected from the array receiver, transforms the signals received by the array receiver into independent spatial measurements, constructs an image using the independent spatial measurements, and outputs a reconstructed image. The array transmitter and the array receiver may each have a plurality of independently controllable metasurface resonant elements.Type: GrantFiled: June 10, 2019Date of Patent: March 7, 2023Assignee: Duke UniversityInventors: Timothy Sleasman, Laura Pulido Mancera, Jonah Gollub, Michael Boyarsky, Thomas Fromenteze, Seyedmohammadreza Faghih Imani, David R.

Publication number: 20210288397Abstract: Systems and methods are disclosed herein for printed cavities for computational microwave imaging and methods or use. According to an aspect, an imaging system includes a printed cavity having a layer having a first surface and a second surface. The printed cavity defines multiple apertures that extend between the first surface and the second surface. The printed cavity also includes a substrate being attached to the first surface of the layer. The substrate is also configured to be fed a guided wave that excites the apertures to produce a radiation pattern for illuminating a scene. The imaging system also include one or more antennas configured to generate a signal for imaging based on the illuminated scene.Type: ApplicationFiled: May 24, 2021Publication date: September 16, 2021Inventors: Okan Yurduseven, Vinay Ramachandra Gowda, Jonah Gollub, David R.
