摘　　要：用格子Boltzmann方法考虑空间不含源项的Maxwell方程组,先构建Maxwell方程组的格子Boltzmann模型并进行数值实验,然后将格子Boltzmann方法与其他传统方法得到的数值解进行比较.结果表明,格子Boltzmann方法是一种求解Maxwell方程组的有效方法.Using the lattice Boltzmann method,we considered Maxwell’s equations without source terms in space.We first constructed a lattice Boltzmann model for Maxwell’s equations and performed numerical experiments.Then we compared the numerical solutions obtained by lattice Boltzmann method with those obtained by other traditional methods.The results show that the lattice Boltzmann method is an effective method for solving Maxwell’s equations.
