High order discontinuous Galerkin methods for time-domain and frequency-domain nanophotonics Open
The discontinuous Galerkin (DG) method is a general numerical modeling approach that has been extensively studied in the last 20 years for the solution of many systems of partial differential equations in physics. Its development for the n…

Influence of spatial dispersion on surface plasmons, nanoparticles, and grating couplers Open
Recent experiments have shown that spatial dispersion may have a conspicuous\nimpact on the response of plasmonic structures. This suggests that in some\ncases the Drude model should be replaced by more advanced descriptions that\ntake spa…

Simulating 3D periodic structures at oblique incidences with discontinuous Galerkin time-domain methods: theoretical and practical considerations Open
In this work, we focus on the development of the use of Periodic Boundary Conditions (PBC) with sources at oblique incidence in a nanophotonics context. In particular, we concentrate on the field transform technique used for time dependent…

Optimization and uncertainty quantification of gradient index metasurfaces [Invited] Open
The design of intrinsically flat two-dimensional optical components, i.e., metasurfaces, generally requires an extensive parameter search to target the appropriate scattering properties of their constituting building blocks. Such design me…

Simulation of three-dimensional nanoscale light interaction with spatially dispersive metals using a high order curvilinear DGTD method Open
In this work, we present and study a flexible and accurate numerical solver in the context of three-dimensional computational nanophotonics. More precisely, we focus on the propagation of electromagnetic waves through metallic media descri…
