Journal ArticleDOI
Third-harmonic generation in the presence of classical nonlocal effects in gap-plasmon nanostructures
TL;DR: In this paper, a numerical study of third-harmonic generation in metal film-coupled nanowires reveals that for subnanometer vacuum gaps, the nonlocality may boost the effective nonlinearity by 5 orders of magnitude as the field penetrates deeper inside the metal than that predicted assuming a purely local electronic response.
Journal ArticleDOI
Analytical modeling of printed metasurface cavities for computational imaging
TL;DR: In this paper, the authors derived simple analytical expressions to model the electromagnetic response of an electrically large printed cavity, which is then used to develop printed cavities for microwave imaging purposes.
Journal ArticleDOI
Experimental comparison between conventional and hybrid long-range surface plasmon waveguide bends
Aloyse Degiron,Sang-Yeon Cho,Cameron Harrison,Nan Marie Jokerst,Claudio Dellagiacoma,Olivier J. F. Martin,David R. Smith +6 more
TL;DR: In this paper, a thin Au stripe embedded in a transparent polymer film was used to characterize long-range surface plasmon waveguide bends at telecom wavelengths (λ=1550 nm).

TL;DR: The National Spherical Torus Experiment (NSTX) has explored the effects of shaping on plasma performance as determined by many diverse topics including the stability of global magnetohydrodynamic (MHD) modes (e.g., ideal external kinks and resistive wall modes), edge localized modes (ELMs), bootstrap current drive, divertor flux expansion, and heat transport.
Journal ArticleDOI
Simulations of hybrid long-range plasmon modes with application to 90° bends
Aloyse Degiron,Claudio Dellagiacoma,James McIlhargey,Gennady Shvets,Olivier J. F. Martin,David R. Smith +5 more
TL;DR: In this article, a simulation of hybrid long-range modes guided by a central metal core and a two-dimensional dielectric slab is performed, and it is shown that these modes are subject to fewer limitations than conventional long-term plasmon modes in terms of field confinement and guiding performance.
