چکیده

In this paper, we study a bybridizable discontinuous Galerkin (HDG) method for the numerical solution of 2D time-harmonic Maxwell’s equations. The formulations are given, and the relationship between the HDG scheme and the upwind flux DG method is also examined. The presented numerical results show the effectiveness of the proposed HDG method especially in comparison to the upwind flux DG method. Key-words: computational electromagnetics, time-harmonic Maxwell’s equations, discontinuous Galerkin method, hybridizable method. in ria -0 06 01 97 9, v er si on 1 21 J un 2 01 1 Une méthode Galerkin discontinue hybride pour les équations de Maxwell en régime harmonique Résumé : Dans ce rapport, nous étudions une méthode Galerkin discontinue hybride (GDH) pour la résolution des équations de Maxwell en régime harmonique en dimension 2. La formulation est de la méthode GDH est présentée et la relation entre la méthode GDH et la méthode GD basée sur un flux décentré est aussi examinée.

A hybridizable discontinuous Galerkin method combined to a Schwarz algorithm for the solution of 3d time-harmonic Maxwell's equation

A Schwarz-type domain decomposition method is presented for the solution of the system of 3d time-harmonic Maxwell equations. We introduce a hybridizable discontinuous Galerkin (HDG) scheme for the discretization of the problem based on a tetrahedrization of the computational domain. The discrete system of the HDG method on each subdomain is solved by an optimized sparse direct (LU factorizatio...

We propose Hybridizable Discontinuous Galerkin (HDG) methods for solving the frequencydomain Maxwell’s equations coupled to the Nonlocal Hydrodynamic Drude (NHD) and Generalized Nonlocal Optical Response (GNOR) models, which are employed to describe the optical properties of nano-plasmonic scatterers and waveguides. Brief derivations for both the NHD model and the GNOR model are presented. The ...
