This paper reviews the recent advances in experiment and theory of the induction of
chiroptical effects, primarily circular dichroism (CD), at the plasmonic and excitonic …

In this article, spectroscopic ellipsometry studies of plasmon resonances at metal–dielectric
interfaces of thin films are reviewed. We show how ellipsometry provides valuable non …

Plasmonic nanoarrays which support collective surface lattice resonances (SLRs) have
become an exciting frontier in plasmonics. Compared with the localized surface-plasmon …

Chiral fields, ie, electromagnetic fields with nonvanishing optical chirality, can occur next to
symmetric nanostructures without geometrical chirality illuminated with linearly polarized …

Recently it was discovered that periodic lattices of metamaterial scatterers show optical
activity, even if the scatterers or lattice show no 2D or 3D chirality, if the illumination breaks …

We present a theoretical study of circular dichroism in the second-harmonic signal of single
dielectric nanostructures with different symmetries and noncentrosymmetric materials. We …

Nanoelectronics is changing the way the world communicates, and is transforming our daily
lives. Continuing Moore's law and miniaturization of low-power semiconductor chips with …

The nature of light as an electromagnetic wave with transverse components has been
confirmed using optical polarizers, which are sensitive to the orientation of the electric field …

We describe a novel plasmonic-mode engineering, enabled by the structural symmetry of a
plasmonic crystal with a metallic oligomer as unit cell. We show how the oligomer symmetry …

A reconfigurable ultra-wideband reflective polarization conversion metasurface (RUR-PCM)
is proposed. The unit cell of the RUR-PCM consists of an anisotropic metal patch …
