Abstract: In the past few decades, metal nanoparticles have attracted a lot of interest due to their ability to confine light in nanometric volumes resulting in interesting applications of plasmonic nanoparticles such as optical sensors. Nanometer-sized metallic particles or structures can strongly absorb and scatter light due to their ability to support surface plasmon resonances - coherent oscillations of surface conduction electrons in response to the electric field of light. In my talk, I will briefly present the theory from a classical electrodynamics perspective and discuss my ongoing research on (a) plasmonic enhancement and circular dichroism response of 2D metamaterials (nanoslits arrays) with circularly polarized light, and (b) optical response of 1D and 2D arrays of gold, silver and aluminium particles with linearly polarized light. Numerical modelling will be based on finite-difference time-domain and coupled-dipole methods.
