We demonstrate optically thin quarter-wave plates built with metasurfaces that generate high-
quality circularly polarized light over a broad wavelength range for arbitrary orientation of the …

Conventional optical components rely on gradual phase shifts accumulated during light
propagation to shape light beams. New degrees of freedom are attained by introducing …

Conventional optical components rely on the propagation effect to control the phase and
polarization of light beams. One can instead exploit abrupt phase and polarization changes …

We demonstrate that polarization conversion in coupled dimer antennas, used in phase
discontinuity metasurfaces, can be tuned by careful design. By controlling the gap width, a …

We report on depolarized light scattering spectra from suspensions of gold nanorods in
terms of the depolarized ratio Ivh/Ivv measured from 400 to 900 nm. For separated, highly …

Optical properties of periodic arrays of nanoholes of a triangular shape with experimentally
realizable parameters are examined in both linear and nonlinear regimes. By utilizing a fully …

With the help of a theoretical model and finite-difference time-domain (FDTD) simulations
based on the hydrodynamic–Maxwell model, we examine the effect of difference-frequency …

We present an extensive experimental and theoretical study of the particle plasmon
resonances of L-shaped gold nanoparticles. For the small characteristic size of the particles …

We consider a biased molecular junction subjected to external time-dependent
electromagnetic field. The field for two typical junction geometries (bowtie antennas and …

We present theoretical models and experiments demonstrating nanoparticle optical
birefringence. The experiments use polarization optical methods to describe the …
