                报告简介

                We propose some energy structure-preserving numerical methods for three-dimensional Maxwell's equations. To avoid solving large scale algebraic equations, we use local one- dimensional (LOD) technique and split the original equations into some LOD subsystems. Then, it results in some efficient numerical scheme by discretizing the LOD equations with Crank-Nicolson scheme in time and high order compact (HOC) method in space. Some benchmark symbols, such as stability, conservation laws of the schemes are analyzed. Some numerical examples confirm the theoretical analysis. Numerical results show that the new schemes not only can simulate the electromagnetic waves, but also energy structure- preserving.
