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 …

We provide experimental evidence of higher multipole (magnetic dipole and electric
quadrupole) radiation in second-harmonic (SH) generation from arrays of metal …

We study the second-harmonic generation by a spherical dielectric nanoparticle covered by
graphene. We demonstrate that a strong nonlinear response is caused by an induced …

We study theoretically the light scattering from metal wires of arbitrary cross section, with
emphasis on the occurrence of plasmon resonances. We make use of the rigorous …

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 multipolar tensor analysis of second-harmonic radiation from arrays of
noncentrosymmetric L-shaped gold nanoparticles. Our approach is based on the …

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 …

We present a detailed multipolar tensor analysis of second-harmonic (SH) generation from
arrays of L-shaped gold nanoparticles. We define three effective nonlinear tensors, which …

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 combined experimental and theoretical study on the laser-induced excitation of surface
plasmon polaritons (SPP) at well-defined step edges of a gold–vacuum interface is …
