Abstract
The mean square tilt angle of a nematic slab with finite anchoring energy and periodic boundary conditions has been theoretically investigated, as a function of the slab geometry and of the reduced extrapolation length. If the anchoring strength is free-surfacelike, the contrast is affected by a loss ≳10% at room temperature if the ratio between the anchoring pitch and the cell thickness is ≳0.5.
