Figure 7From: An a priori error estimate for interior penalty discretizations of the Curl-Curl operator on non-conforming meshes Smallest/Largest non-zero eigenvalues vs. the rotation angle θ for \(\pmb{h=0.359644}\) , \(\pmb{\varepsilon=0}\) , \(\pmb{\mu\equiv1}\) . The discretization is based on \(R^{2}\) edge functions.Back to article page
