Critique of optical negative refraction superlensing [PDF]
, 2011 Has the ten-year old quest for the optical superlens, based on Veselago’s hypothesis of negative refraction, been a chimera? We argue that Pendry’s alternative prescription of the silver superlens is nothing more than an application of the natural ...

Effect of heavy metals (Ni, Cu, Pb) doped ZnO on the nonlinear optical properties
Materials Research Express, 2020 In this paper, the non-linear optical properties of undoped and doped ZnO thin films were investigated. The films were doped with Ni, Pb, and Cu. an increase in the refractive index against wavelength is apparent for all films up to a certain value of ...

Figure of merit for design of ε-near-zero metamaterials with enhanced Kerrtype nonlinearities [PDF]
EPJ Web of Conferences, 2023 Metamaterials are artificial media designed to display properies going beyond those of ordinary materials. Particularly interesting are ε-near-zero (ENZ) media with real part of the permittivity going to zero in a certain spectral range.

Ray-optical refraction with confocal lenslet arrays [PDF]
, 2008 Two parallel lenslet arrays with focal lengths f1 and f2 that share a common focal plane (that is, which are separated by a distance f1+f2) can refract transmitted light rays according to Snell's law, but with the 'sin's replaced with 'tan's. This is the
