Metallic nanoparticles can be used to create artificial structures known as metamaterials. They possess unique physical properties not observed in nature and enable novel applications such as superlenses breaking the diffraction limit, nanoscale optical antennas and optical cloaking. In the study of nonlinear optics metamaterials are interesting since they can exhibit strong local fields to enhance nonlinear effects. Metamaterials can also be fabricated with broken symmetries to enable even-order nonlinear effects such as second-harmonic generation (SHG) which cannot occur in centrosymmetric media such as most natural materials. In this work arrays of L- and T-shaped gold nanoparticles are studied. The shapes have one symmetry plane and ar...
