The authors analyze a high efficient scheme for the Steklov eigenvalue problem. They use a two-grid discretization scheme with nonconforming Crouzeix-Raviart elements. They also use the Nitsche-Lascaux-Lesaint technique to prove an asymptotically optimal accuracy in a certain Sobolev space. Numerical examples are also discussed.
