This paper considers the time-harmonic Maxwell's equations with anisotropic complex coefficients in a bounded Lipschitz domain. We first establish the $W^{1,r}$ estimates for divergence form equations with the coefficients being the small complex perturbations of real symmetric matrices in Lipschitz domains. As an application, we then show the $L^r$ estimates of electric and magnetic fields for $\frac{3}{2}-\varepsilon(\Omega)<r<3+\varepsilon(\Omega)$, where $\varepsilon(\Omega)>0$ depends on the Lipschitz character of the domain $\Omega$.

Lipschitz域中具有复系数的麦克斯韦方程组的$ L ^ r $估计

SIAM数学分析杂志,第52卷,第6期,第6140-6154页,2020年1月。
本文考虑有界Lipschitz域中具有各向异性复系数的时谐Maxwell方程。我们首先建立散度形式方程的$ W ^ {1,r} $估计,其系数为Lipschitz域中实对称矩阵的小复扰动。作为应用,然后显示$ \ frac {3} {2}-\ varepsilon(\ Omega)<r <3+ \ varepsilon(\ Omega)$的电场和磁场的$ L ^ r $估计值,其中$ \ varepsilon(\ Omega)> 0 $取决于域$ \ Omega $的Lipschitz字符。
