A Spectrally-Accurate FVTD Technique for Complicated Amplification and Reconfigurable Filtering EMC Devices
Nikolaos V. Kantartzis,Stylianos D. Assimonis,Antonios Lalas,Jonathan B. Scott,Christos S. Antonopoulos +4 more
TL;DR: The consistent and computationally economical analysis of demanding amplification and filtering structures is introduced in this paper via a new spectrally-precise finite-volume time-domain algorithm that employs a fully conservative field flux formulation to derive electromagnetic quantities in areas with fine structural details.

TL;DR: In this paper, a stochastic spectrally-controllable methodology for the precise design of 3D nanomedia and graphene-based components with statistical parameters is introduced, and a set of reduced-order models for a hybrid finite-difference time-domain/vector finite-element timedomain (FDTD/VFETD) formulation is developed.
