Аннотация доклада:
We have studied experimentally and computationally the second harmonic generation (SHG) from magnetic metasurfaces exhibiting electric and magnetic dipole resonances in the visible/near IR spectral range. The spectroscopy of the intensity and phase of the second harmonic wave generated by the samples show an increase of the SHG efficiency as the fundamental wavelength is being tuned in vicinity of the magnetic resonance of the metasurface. This is accompanied by the π/2 phase shift of the SHG wave. The role of magnetic dipole and electric quadruple moments in SHG response is discussed.
