The second-harmonic generation of 150 nm spherical gold nanoparticles is investigated
both experimentally and theoretically. We demonstrate that the interference effects between …

Over the last fifteen years, a series of theoretical and experimental investigations have
demonstrated the usefulness of circular geometries to tailor second‐order nonlinear optical …

The theory of optical second-harmonic (SH) scattering from finite cylinders of arbitrary size,
orientation, and crystallographic structure is developed within the Rayleigh-Gans-Debye …

We present a comprehensive theoretical study of the second harmonic generation (SHG) in
metamaterials consisting of arbitrary distributions of cylindrical nanowires made of …

We study second-harmonic generation arising from surface nonlinearity at a metal-dielectric
interface using a spectral decomposition method. Since our method avoids the need to …

Airy beams represent an important type of non-diffracting beams—they are the only non-
diffracting wave in one dimension, and thus they can be produced with a cylindrical …

The theory of surface-second-harmonic generation in a dielectric microsphere using
whispering-gallery modes (WGMs) is developed. The second-order nonlinearity is restricted …

A numerical technique for studying the generation of second-harmonic radiation in the
interaction of light with two-dimensional particles of arbitrary shape is described. The …

The spin and orbital angular momentum carried by electromagnetic pulses open new
perspectives to control nonlinear processes in light–matter interactions, with a wealth of …

We propose a numerical method, based on surface integral equations (SIE), for evaluating
the second harmonic (SH) scattering by metal nanoparticles (NPs) of arbitrary shape …
