Schematic of experiment. a Schematic of the wall shape with relevant parameters: radius of curvature R, amplitude A, and wavelength λ. b Schematic of the experimental setup (N denotes rubbing direction, T denotes thickness of the cell). c, d Cross polarized images of liquid crystal near the wavy wall with the long axis either (c) at a 45° angle to the polarizer or (d) perpendicular to the polarizer. The scale bars are 20 μm
