Abstract:

We propose and analyze an approximation technique for the Maxwell eigenvalue problem using $\mathbf {H}^1$-conforming finite elements. The key idea consists of 󠀼span style=󠀢color:black󠀢󠀾considering a mixed method󠀼/span󠀾 controlling the divergence of the electric field in a fractional Sobolev space $H^{-\alpha }$ with $\alpha \in (\frac 12,1)$. The method is shown to be convergent and spectrally correct.
