TL;DR: This work considers a dielectric material that exhibits an optical Kerr effect as the spacer layer and numerically calculates the optical bistability of a metasurface using the finite element method (FEM) and proposes this method as a tool for designing all-optical switches and modulators.

TL;DR: The theory of cavity-backed metasurface antennas is explained, and frequency diverse imaging is demonstrated with a pair of these antennas.

TL;DR: In this article, a morphology-correlated surface-enhanced Raman scattering (SERS) from molecules on the surface of individual clusters of gold nanoparticles of two types was reported.

TL;DR: In this paper, the authors investigated the scaling of the nonlinear response of the surface plasmon polariton at a metal/dielectric interface, where the metal and dielectric present optical nonlinearity.

TL;DR: In this paper, an investigation of fluctuating pixels resulting from proton irradiation of an E2V Technologies CCD47-20 device is presented, and the characteristics of the observed flickering pixels are discussed in detail and the proposed models explaining the mechanism behind the phenomena are viewed in light of the collected data.
