Experimental realization of an epsilon-near-zero metamaterial at visible wavelengths
TL;DR: In this article, the optical phase advance during propagation can be very small in metamaterials with dielectric permittivities close to zero at visible wavelengths, and the authors show that the optical phases can be accelerated by very small amounts.

Highly efficient GaAs solar cells by limiting light emission angle
TL;DR: In this article, the authors show that limiting the emission angle of a high-quality GaAs solar cell is a feasible route to achieving power conversion efficiencies above 38% with a single junction.
Localized surface-plasmon resonances in periodic nondiffracting metallic nanoparticle and nanohole arrays
TL;DR: In this paper, the optical response of periodic non-iffracting metallic nanoparticles and nanohole arrays is compared and it is shown that the response of the nanoparticle arrays is largely independent of interparticle separation.
Localized surface-plasmon resonances and negative refractive index in nanostructured electromagnetic metamaterials
TL;DR: In this article, the authors explore the extent to which the concept of localized surface-plasmon resonances can be used to explain the optical response of complementary electromagnetic metamaterials in the visible.
Electromagnetic resonances of a multilayer metal-dielectric stack
TL;DR: In this article, the electromagnetic resonances of multilayer metal-dielectric stacks are investigated and it is shown that the response of the structure is largely independent of its overall length, and only the geometry of the unit cell is important.
