Journal ArticleDOI
Design and fabrication of a metamaterial gradient index diffraction grating at infrared wavelengths.
TL;DR: The design, fabrication and characterization of an artificially structured, gradient index metamaterial with a linear index variation of Δn ~ 3.0 is demonstrated, which has the potential to enable compact infrared diffractive and gradient index optics, as well as more exotic transformation optical media.
Journal ArticleDOI
Overcoming phase mismatch in nonlinear metamaterials [Invited]
Alec Rose,David R. Smith +1 more
TL;DR: In this article, the authors present an overview of phase matching solutions for wave-mixing processes in nonlinear metamaterials and divide them into conventional techniques (anomalous dispersion, birefringence, and quasi-phase matching) and metamatter-inspired techniques (negative-index and index-near-zero phase matching).
Journal ArticleDOI

TL;DR: The National Spherical Torus Experiment (NSTX-U) as mentioned in this paper has been used to test physics theories for next-step tokamak operation, including ITER.
Journal ArticleDOI
Application of range migration algorithms to imaging with a dynamic metasurface antenna
Laura Pulido-Mancera,Thomas Fromenteze,Timothy Sleasman,Michael Boyarsky,Mohammadreza F. Imani,Matthew S. Reynolds,David R. Smith +6 more
TL;DR: The range migration algorithm is adapted for use with dynamic metasurfaces and a preprocessing step is proposed that ultimately allows for expression of measurements in the spatial frequency domain, from which the fast Fourier transform can efficiently reconstruct the scene.
Journal ArticleDOI
Transformation optics with photonic band gap media.
TL;DR: PC cloaks and other TO devices operating at visible wavelengths can be constructed from optically transparent substances such as glasses, whose attenuation coefficient can be as small as 10 dB/km, suggesting the TO design methodology can be applied to the development of optical devices not limited by the losses inherent to metal-based, passive metamaterials.
