Abstract:

In this paper, spectral analysis on the saddle point linear systems from the finite element discretization of the mixed formulation of the time-harmonic Maxwell equations are presented. Theoretical analysis shows that all the eigenvalues of the relational coefficient matrix are strongly clustered under certain conditions.

Key words: Maxwell equations, Saddle point systems, Eigenvalue
