摘要：
We present recent advances in the development of a Discontinuous Galerkin Time Domain (DGTD) solver for computational nanophotonics, focusing on metallic nanostructures irradiated by laser pulses. After a brief reminder about the DGTD method in the nano-optics framework, we discuss a nonlocal dispersion model for the electron gas, which accounts for spatial dispersion that becomes important for structure sizes between 2 nm and 25 nm. Then, we deal with the numerical modeling of this nonlocal model when coupled to the 3D Maxwell's equations in time-domain. We conclude by assessing our implementation with analytical solutions and provide selected numerical examples.
