Dynamic Metasurface Antennas for MIMO-OFDM Receivers with Bit-Limited ADCs
Hanqing Wang, Nir Shlezinger, Yonina C. Eldar +4
The combination of orthogonal frequency modulation (OFDM) and multiple-input multiple-output (MIMO) systems plays an important role in modern communication systems. In order to mee…
Implementation and Characterization of a Two-Dimensional Printed Circuit Dynamic Metasurface Aperture for Computational Microwave Imaging
Timothy Sleasman, Mohammadreza F. Imani, Aaron V. Diebold +3
We present the design, fabrication, and experimental characterization of a two-dimensional, dynamically tuned, metasurface aperture, emphasizing its potential performance in comput…
Artificial Neural Network with Physical Dynamic Metasurface Layer for Optimal Sensing
Philipp del Hougne, Mohammadreza F. Imani, Aaron V. Diebold +2
We address the fundamental question of how to optimally probe a scene with electromagnetic (EM) radiation to yield a maximum amount of information relevant to a particular task. Ma…
Grating Lobe Suppression in Metasurface Antenna Arrays with a Waveguide Feed Layer
Michael Boyarsky, Mohammadreza F. Imani, David R. Smith
Metasurface antenna arrays, formed by tiling multiple metasurface subapertures, offer an alternative architecture to electrically large beamsteering arrays often used in radar and…
Dynamic Metasurface Antennas for Uplink Massive MIMO Systems
Nir Shlezinger, Or Dicker, Yonina C. Eldar +3
Massive multiple-input multiple-output (MIMO) communications are the focus of considerable interest in recent years. While the theoretical gains of massive MIMO have been establish…
