A New Numerical Flux in Discontinuous Galerkin Time- Domain Method for Tellegen Media

The magneto electric coupling of Tellegen media makes formulating discontinuous Galerkin time-domain (DGTD) extensions a challenge. In this paper, we present a new upwind flux for Tellegen media. A novel DGTD formulation equipped with the new flux is presented to model the interaction of an electromagnetic wave with arbitrarily shaped three-dimensional Tellegen objects. The new upwind flux has been validated by means of numerical experiments and has shown good agreement.
