Toward One-Way Smoke: Synthesis of Copper-Based Microclubs with Asymmetric Scattering and Absorption

Journal Article Advanced Functional Materials · July 17, 2024 The ultimate goal of this work is to create an engineered aerosol that acts as one-way smoke, i.e. it creates an asymmetric vision environment in which the ability to image objects depends on the viewing direction. To this end, a rapid, one-pot synthesis o ... Full text Cite

Implementation and Characterization of a Two-Dimensional Printed Circuit Dynamic Metasurface Aperture for Computational Microwave Imaging

Journal Article IEEE Transactions on Antennas and Propagation · April 1, 2021 We present the design, fabrication, and experimental characterization of a 2-D, dynamically tuned, metasurface aperture, emphasizing its potential performance in computational imaging applications. The dynamic metasurface aperture (DMA) consists of an irre ... Full text Cite

Grating lobe suppression in metasurface antenna arrays with a waveguide feed layer.

Journal Article Optics express · August 2020 Metasurface antennas offer an alternative architecture to electrically large beamsteering arrays often used in radar and communications. The advantages offered by metasurfaces are enabled by the use of passive, tunable radiating elements. While these metam ... Full text Cite

Review of Metasurface Antennas for Computational Microwave Imaging

Journal Article IEEE Transactions on Antennas and Propagation · March 1, 2020 This article covers recent advances in the fusion of metasurface antenna design and computational imaging (CI) concepts for the realization of imaging systems that are planar, fast, and low cost. We start by explaining the operation of metamaterial antenna ... Full text Cite

Computational through-wall imaging using a dynamic metasurface antenna

Journal Article OSA Continuum · December 15, 2019 We present a study of computational through-wall imaging using a dynamically reconfigurable metasurface antenna (DMA). The DMA consists of a single-feed, electrically-large microstrip line, loaded with individually addressable metamaterial radiators. Each ... Full text Cite

Experimental Synthetic Aperture Radar with Dynamic Metasurfaces

Journal Article IEEE Transactions on Antennas and Propagation · December 1, 2017 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 1-D microstrip waveguide with complementary electric resonator (cELC) elements patterned ... Full text Cite

Generalized range migration algorithm for synthetic aperture radar image reconstruction of metasurface antenna measurements

Journal Article Journal of the Optical Society of America B: Optical Physics · December 1, 2017 Waveguide-fed dynamic metasurface antennas (DMAs) can be used in a variety of synthetic aperture radar (SAR) modalities for microwave and millimeter-wave imaging. The DMA consists of an electrically large array of resonant, dynamically reconfigurable metam ... Full text Cite
