摘要：
We study by coarse-graining methods, the dependence of the nematic anchoring energy on the scale at which the orientation of the nematic director is resolved. We obtain a relationship allowing to compare anchoring measurements with different resolutions performed on the same nematic-substrate system. Our theory also permits to calculate the effective macroscopic anchoring corresponding to a given micro-fabricated surface aligning pattern, and to determine the limitations of this effective description.
