Abstract
With recently developed software called "Smuthi", a linear space-limited model is constructed in an all-dielectric metasurface made of AlGaAs nanocylinders on aluminium oxide substrate, this structure has been demonstrated to support very strong nonlinear optical effects such as second-harmonic generation (SHG) with efficiency around 10-4 at magnetic dipole resonance wavelength (around 1600nm). This model includes border effects, the contribution of lateral walls representing the finite structure same as the experimental phase.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
