Abstract
We observe textures on polar smectic films, using a new approach to achieve the polar geometry. We concentrate on 2D confined circular domains, for which we observed a “boojum” pattern and a previously unobserved spiral texture that reverses it direction of winding at a critical radius. The mapping of the c-vector is given in each case. The textures are understood in light of a free energy with one additional Ksb bulk term and one additional λs boundary term.
