Electronically Steered Nyquist Metasurface Antenna
Michael Boyarsky, Timothy Sleasman, Mohammadreza F. Imani +2
Mobile devices, climate science, and autonomous vehicles all require advanced microwave antennas for imaging, radar, and wireless communications. The cost, size, and power consumpt…
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…
Polarizability Extraction for Waveguide-Fed Metasurfaces
Laura Pulido-Mancera, Patrick T. Bowen, Nathan Kundtz +2
We consider the design and modeling of metasurfaces that couple energy from guided waves to propagating wavefronts. This is a first step towards a comprehensive, multiscale modelin…
