Searching for Better Plasmonic Materials
Paul R. West,Satoshi Ishii,Gururaj V. Naik,Naresh Kumar Emani,Vladimir M. Shalaev,Alexandra Boltasseva +5 more
TL;DR: A comparative study of various materials including metals, metal alloys and heavily doped semiconductors is presented and an approach for realizing optimal plasmonic material properties for specific frequencies and applications is outlined.
Journal ArticleDOI
All-dielectric subwavelength metasurface focusing lens
Paul R. West,James L. Stewart,Alexander V. Kildishev,Vladimir M. Shalaev,Vladimir V. Shkunov,Friedrich Strohkendl,Yuri A. Zakharenkov,Robert K. Dodds,Robert W. Byren +8 more
TL;DR: A set of lens designs with reduced reflection and tailorable phase gradients have been developed and tested, demonstrating focal distances of a few hundred microns, beam area contraction ratio up to three, and insertion losses as low as 11%.
Journal ArticleDOI
Adiabatically tapered hyperbolic metamaterials for dispersion control of high-k waves.
Paul R. West,Nathaniel Kinsey,Marcello Ferrera,Marcello Ferrera,Alexander V. Kildishev,Vladimir M. Shalaev,Alexandra Boltasseva +6 more
TL;DR: This method of in-plane outcoupling acts as a bridge through which waves can cross between the regimes of low-K waves in classical dielectric materials and the high-k waves in HMMs with strongly reduced reflective losses.
Journal ArticleDOI
Angled physical vapor deposition techniques for non-conformal thin films and three-dimensional structures
Zhuoxian Wang,Zhuoxian Wang,Paul R. West,Xiangeng Meng,Nathaniel Kinsey,Vladimir M. Shalaev,Alexandra Boltasseva +6 more
TL;DR: In this paper, the authors report several techniques utilizing angled physical vapor deposition to obtain unique and complex 3D structures such as films with tapered thickness on planar substrates, tapered or uniform films on curved surfaces, and 3D nanorod arrays.
