Second harmonic generation by excitation of coupled two dimensional silver nanoresonantors

Here we report results of calculations performed on Silver coupled 2D-nanoresonators (NR). Coupling is responsible for the formation of resonant modes that can be localized on small portions of the structure or distributed over the whole structure. Different field profiles can be obtained by varying the parameters of the input field (i.e. the wavelength). The radiation pattern of the generated SH field is obtained by considering linear scattering and the structure behaves as an antenna for the SH field.
