anisotropic Scientific  

/ ăn-ī′sə-trō′pĭk,-trŏp′ĭk,ăn′ī- /

1. Differing according to orientation, as light scattered by a liquid crystal; light striking the liquid crystal's surface at a 90° angle might not be reflected (so the surface appears dark when viewed head-on), while light striking it at shallower angles is reflected (so the surface appears illuminated when viewed from a shallow angle).

2. Compare isotropic
