Journal ArticleDOI
Large Metasurface Aperture for Millimeter Wave Computational Imaging at the Human-Scale.
Jonah N. Gollub,Okan Yurduseven,Kenneth P. Trofatter,Daniel Arnitz,Mohammadreza F. Imani,Timothy Sleasman,Michael Boyarsky,Alec Rose,Andreas Pedross-Engel,Hayrettin Odabasi,Tomas Zvolensky,Guy Lipworth,David J. Brady,Daniel L. Marks,Matthew S. Reynolds,David R. Smith +15 more
TL;DR: A low-profile holographic imaging system at millimeter wavelengths based on an aperture composed of frequency-diverse metasurfaces is demonstrated and computational methods and calibration approaches that enable rapid and accurate imaging performance are introduced.
Journal ArticleDOI
Synthetic aperture radar with dynamic metasurface antennas: a conceptual development.
Michael Boyarsky,Timothy Sleasman,Laura Pulido-Mancera,Thomas Fromenteze,Andreas Pedross-Engel,Claire M. Watts,Mohammadreza F. Imani,Matthew S. Reynolds,David R. Smith +8 more
TL;DR: It is shown that electronically tuned DMAs can generate steerable, directive beams for traditional stripmap and spotlight SAR imaging modes, which eliminates the need for mechanical gimbals and phase shifters, simplifying the hardware architecture of a SAR system.
Journal ArticleDOI
Orthogonal Coded Active Illumination for Millimeter Wave, Massive-MIMO Computational Imaging With Metasurface Antennas
Andreas Pedross-Engel,Daniel Arnitz,Jonah N. Gollub,Okan Yurduseven,Kenneth P. Trofatter,Mohammadreza F. Imani,Timothy Sleasman,Michael Boyarsky,Xiaojie Fu,Daniel L. Marks,David R. Smith,Matthew S. Reynolds +11 more
TL;DR: It is shown that OCAI is robust to code amplitude and code phase imbalance introduced by imperfect transmitter (TX) and receiver (RX) hardware, while also mitigating common impairments of low cost direct-conversion receivers, such as RX selfjamming and DC offsets.
Journal ArticleDOI
Enhanced Resolution Stripmap Mode Using Dynamic Metasurface Antennas
TL;DR: A new SAR mode of operation is proposed, which improves resolution while maintaining good SNR and a large scene size, and leverages the unique properties of dynamic metasurface antennas to subsample a large virtual beamwidth utilizing multiple small distinct antenna beams.
Journal ArticleDOI
X-band SAR imaging with a liquid-crystal-based dynamic metasurface antenna
TL;DR: In this paper, a dynamic metasurface antenna (MSA) was proposed for synthetic aperture radar (SAR) imaging using an X-band (10-13.7 GHz) dynamic antenna.
