提出了一种基于Gauss-Lobatto-Legendre多项式的高阶三维混合谱元方法(SEM),用于消除矢量麦克斯韦本征值问题数值解中的伪本征模.为了抑制传统有限元和高阶SEM中存在的所有零和非零寄生模式,该方法不仅采用混合阶卷曲协调矢量基函数作为电场强度,而且还包括弱形式的高斯定律给出的无发散条件。数值算例验证了混合SEM不含任何伪本征模,且具有解析本征向量的谱精度。
A high-order 3-D mixed spectral-element method (SEM) based on Gauss-Lobatto-Legendre polynomials in the mixed finite-element framework is proposed to remove the spurious eigenmodes in the numerical solution of the vector Maxwell eigenvalue problem with inhomogeneous, lossy isotropic, and anisotropic media. In order to suppress all zero and nonzero spurious modes that exist in the conventional finite-element and higher order SEMs, the proposed method not only employs the mixed-order curl-conforming vector basis functions for the electric field intensity, but also includes the divergence-free condition given by Gauss' law in a weak form. Several numerical examples are given to verify that the mixed SEM is free of any spurious eigenmodes and has spectral accuracy with analytic eigenvectors.
