• . However, owing to the polarization and far-field interference, a silencing of the SHG is observed for decreasing gap sizes [53]. This effect is further studied in [54] using the surface integral equation method. On the other hand, the generation of higher harmonics by a dielectric nanostructure can be

• in the SHG from gold nanoantennas using a surface integral equation method. To investigate this phenomenon in detail, various geometries have been considered, including nanoantennas with cylindrical and rectangular arms, as well as surface defects. To quantify the “silencing” effect, a new numerical

• nanostructures corresponds to the limited far-field second harmonic radiation despite the huge fundamental electric field enhancement in the interstice between two plasmonic nanoparticles forming a nanodimer. In this article, we report a comprehensive investigation of this effect using a surface integral

The wavelength-dependent extinction spectrum of one nano-triangle is calculated using the ‘surface integral equation’ method [30]. The response of the triangle
