Simulating Plasmonic Effects with COMSOL Multiphysics® - Archived
Plasmons in two-dimensional electron systems, including graphene, have recently attracted attention for their potential role in terahertz (THz) technology. In particular, drifting plasmons have been shown to be candidates for THz wave generation. To this end, the development of comprehensive modeling techniques is necessary for the understanding of plasmon dynamics.
In this webinar, we will discuss how the scattering of 2D plasmons by interfaces, in the absence and in the presence of direct current, can be modeled with the COMSOL Multiphysics® software. We will first discuss the off-the-shelf functionality in COMSOL Multiphysics® for this scenario, and then describe a more advanced, bespoke implementation, leading to excellent agreement with theoretical models.
This presentation will include a live demonstration and a Q&A session.
