We use two-beam second-harmonic generation to separate the surface (electric dipole
origin) and bulk (magnetic dipole and electric quadrupole origin) contributions to the second …

We present a theoretical approach to the study of second-and third-harmonic generation
from metallic structures and nanocavities filled with a nonlinear material in the ultrashort …

In this paper, we develop a classical electrodynamic theory to study the optical nonlinearities
of metallic nanoparticles. The quasi free electrons inside the metal are approximated as a …

We present a numerical investigation of the second-order nonlinear optical properties of
metal-based metamaterial nanoresonators. The nonlinear optical response of the metal is …

Because of its high surface and interface sensitivity, the nonlinear optical technique of
second harmonic generation (SHG) is a designated method for investigating nanostructured …

Here we report the experimental observation of circular dichroism in the second-harmonic
field<? format?>(800–400 nm conversion) generated by self-organized gold nanowire …

In this study, an absorber with the characteristics of high absorptivity and ultra-wideband
(UWB), which was ranged from the visible light range and near-infrared band, was designed …

Classical nonlocality in conducting nanostructures has been shown to dramatically alter the
linear optical response by placing a fundamental limit on the maximum field enhancement …

We study optical second harmonic generation from metallic dipole antennas with narrow
gaps. Enhancement of the fundamental-frequency field in the gap region plays a marginal …

We discuss propagation effects in realistic, transparent, metallodielectric photonic band gap
structures in the context of negative refraction and super-resolution in the visible and near …
