Embodiments calculate birefringence of a material. One such embodiment constructs one or more three-dimensional structural models of one or more compounds forming a material. Each constructed three-dimensional structure model is aligned along a molecular axis, and one or more tilt angles of each aligned three-dimensional structure model are set. A molecular polarizability tensor for each three-dimensional structural model having the set tilt angle is then calculated. One embodiment takes into account anisotropy by determining the aspect ratio by measuring the width and length of each model having the set tilt angle. To continue, birefringence of the material is calculated based on the determined molecular polarizability tensor of the one or more models. Embodiments may be used to simulate, optimize, and design real-world objects, such as in optimization, to select materials for telephone displays that comply with performance/manufacturing requirements. 实施例计算材料的双折射。一个此类实施例构建形成材料的一种或多种化合物的一个或多个三维结构模型。每个构建的三维结构模
