Phase transitional behaviors of V-shaped liquid crystal molecule in electric field [PDF]
, 2016 作为物质的第四态，液晶如今被广泛应用于光电显示器件之中。液晶态，同时具有类似于液体的流动性质和类似于晶体的有序性与各向异性。在热致液晶中，我们可以根据分子的有序性和排列形式的不同，将其分为向列相液晶、近晶相液晶和胆甾相液晶。由于向列相液晶的稳定结构、较低粘度和较宽的工作温度范围，而被应用的最为广泛。 向列相液晶可存在三种状态—双轴相、单轴相和各向同性相。过去几年，双轴向列相液晶在快速响应显示器件中的应用前景引起了广泛的关注，因为其沿着辅轴转动比沿着主轴转动节能且快捷的多。实际上，在理论和实验中 ...

Dianci bileiqi, 2018 采用3D-FDTD电磁场数值算法对建筑物顶部雷电电磁场的畸变效应进行研究。考虑雷击高塔情况下,分析雷电电磁场在建筑物顶部的波形特征,探讨不同高度建筑物对电磁场波形的影响。仿真结果表明,当场点处存在建筑物时,雷电垂直电场的畸变效应较为显著,建筑物不仅会增强垂直电场的峰值,还会影响电场波形的多峰特征。而角向磁场的畸变效应较弱,建筑物仅对其峰值有一定的影响,而对其波形多峰特征的影响可以忽略。
