The birefringent texture of nematic liquid crystals confined to capillary tubes with square cross-section
The structure of nematic liquid crystal director fields in supramicrometer capillary tubes with square cross-section is studied using polarizing optical microscopy. Frank elastic theory is used to determine theoretical director configurations for this geometry.
