Optimizing Polarizability Distributions for Metasurface Apertures with Lorentzian-Constrained Radiators
Patrick T. Bowen, Michael Boyarsky, Laura M. Pulido-Mancera +3
We present a design strategy for selecting the effective polarizability distribution for a metasurface aperture needed to form a desired radiation pattern. A metasurface aperture c…
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…
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…
Computational polarimetric microwave imaging
Thomas Fromenteze, Okan Yurduseven, Michael Boyarsky +3
We propose a polarimetric microwave imaging technique that exploits recent advances in computational imaging. We utilize a frequency-diverse cavity-backed metasurface, allowing us…
