In this review article, we provide an overview of recent research activities in the study of
plasmonic optical properties of metal nanostructures with emphasis on understanding the …

Applications of the interface-selective methods of second harmonic (SHG) and sum
frequency (SFG) spectroscopy to the investigation of equilibrium and time-dependent …

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 …

Optical properties are among the most fascinating and useful properties of nanomaterials
and have been extensively studied using a variety of optical spectroscopic techniques. A …

We present a theory for second-order nonlinear light scattering from spherical particles
using source waves of arbitrary frequency and direction based on a combination of linear …

The shape and alignment of silver nanoparticles embedded in a glass matrix is controlled
using silicon ion irradiation. Symmetric silver nanoparticles are transformed into anisotropic …

Optical second-harmonic (SH) generation from the surface of spherical particles of radii
much smaller than the optical wavelength has been investigated experimentally. Angle-and …

We present in detail the formulation of the ab initio theory we have developed for the
calculation of the macroscopic second-order susceptibility χ (2). We find a general …

We present a theoretical framework for the generation and scattering of second-harmonic
and sum-frequency light from the surface of particles of arbitrary shape in the limit of low …

We describe second-order vibrational sum frequency scattering from a spherical isotropic
particle covered with a dielectric film. We use the concept of an effective particle …
