Control of the Scattering Properties of Complex Systems By Means of Tunable Metasurfaces
Jared Erb, David Shrekenhamer, Timothy Sleasman +2
We demonstrate the ability to control the scattering properties of a two-dimensional wave-chaotic microwave billiard through the use of tunable metasurfaces located on the interior…
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…
Single-Frequency Microwave Imaging with Dynamic Metasurface Apertures
Timothy Sleasman, Michael Boyarsky, Mohammadreza F. Imani +3
Conventional microwave imaging schemes, enabled by the ubiquity of coherent sources and detectors, have traditionally relied on frequency bandwidth to retrieve range information, w…
Experimental Synthetic Aperture Radar with Dynamic Metasurfaces
Timothy Sleasman, Michael Boyarsky, Laura Pulido-Mancera +4
We investigate the use of a dynamic metasurface as the transmitting antenna for a synthetic aperture radar (SAR) imaging system. The dynamic metasurface consists of a one-dimension…
