(a) The spatial distribution of the normalized nonlinear currents inside the nanocylinder at \(\omega _{3}\): modulus (left panel) and orientation (right panel). (b) Far-field emission of the AlGaAs nanoantenna in the THz. (c) The normalized effective surface currents in the gold SRR at \(\omega _{3}\). (d) Radiation pattern of the SRR in the THz. The plots are obtained by using COMSOL Multiphysics v5.5—https://www.comsol.com.
