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.

TL;DR: These studies suggest that interferon is efficacious in the treatment of resistant and persistent condyloma acuminatum, and that the biologic side effects were dose-related, well tolerated, and not life-threatening.

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.

TL;DR: A calibration scheme is proposed that compares the measured versus simulated scattered field from a cylinder and calculates a compensating phase difference to be applied at each of the panels comprising the system, avoiding a more laborious manual calibration step.

TL;DR: In this article, the design, fabrication, and experimental characterization of a 2D, dynamically tuned, metasurface aperture is presented, emphasizing its potential performance in computational imaging applications, and the singular value spectrum of the sensing matrix over a variety of operating parameters, such as the number of metamaterial elements, number of masks, and number of radiating elements.
