Printed cavities for computational microwave imaging and methods of use
TL;DR: In this paper, the authors describe a printed cavity with multiple apertures that extend between the first surface and the second surface, and a substrate being attached to the substrate of the layer.

Plasmonic Nanocomposits for Enhanced Four-Wave Mixing Generation
TL;DR: In this article, third-order nonlinear response and strong field enhancement in gold nanocomposites were utilized to analyze the enhanced effective nonlinear susceptibility and efficiency of the FWM process in the evanescent and propagating excitation regimes.
Proceedings ArticleDOI
Second Harmonic Generation by Metamagnetics: Interplay of Electric and Magnetic Resonances
Rohith Chandrasekar,Naresh Kumar Emani,Alexei S. Lagutchev,Vladimir M. Shalaev,Alexander V. Kildishev,Cristian Ciracì,David R. Smith +6 more
TL;DR: In this paper, the interplay of electric and magnetic resonances in a metamaterial has been studied to measure their independent contributions to second-harmonic generation, and experiments indicate evident contribution to SHG from fundamental magnetic field.
Journal ArticleDOI
Scoping study of detecting high harmonic fast waves in NSTX-U hot core plasma directly using beam emission spectroscopy.
TL;DR: In this paper, the authors used radio frequency (RF) full wave simulation to explore the feasibility of generating a density beat oscillation formed by high harmonic fast waves (HHFWs) in the National Spherical Tokamak Experiment-Upgrade (NSTX-U) and of measuring it numerically with 2D beam emission spectroscopy (BES).
