Abstract：

In this talk, we will introduce our recent advances in the multiscale modeling and algorithms for the electromagnetic properties of heterogeneous materials. First, we will briefly talk about the fundamental physical questions and the mathematical models from the classical electrodynamics to the semi-quantum models, then to the quantum electrodynamics (QED) and the quantum chromodynamics (QCD). Meanwhile, we will introduce some important studies about the multiscale analysis and algorithms for the classical Maxwell's equations and for the semi-quantum models. Second, we focus on discussing the multiscale method for the Maxwell's equations in the heterogeneous dispersion media including metamaterials and negative index materials. Third, the homogenization method and the multiscale asymptotic method for the semi-quantum models such as Schr?dinger-Poisson system, Maxwell- Schr?dinger system and Maxwell-Dirac system with rapidly oscillating discontinuous coefficients are presented. It originates from the interaction of the matter field and the electromagnetic field in materials science. Finally, the numerical results and some typical applications are reported.

Ps：This talk is based on the joint work with Dr. Lei Zhang, Dr. Yongwei Zhang,

Dr. Chupeng Ma and Prof. Yanping Lin.
