Efficient multiphysics and multiscale FDTD methods for terahertz plasmonic devices

Abstract

Modeling terahertz plasmonic devices is a multiphysics and multiscale problem. Due to high mesh density in the electron transport regions, the simulation times are long. In this work, we develop hybrid coupled finite difference time domain (FDTD) methods for fast design of terahertz plasmonic devices. The methods employ implicit solution (using Alternate Direction Implicit), coupled with hydrodynamic modeling for plasmonic applications. The theory, simulation and time-improvement related results will be presented at the conference.
