论文摘要
提出了对激光诱导的传输货物微端加热的理论研究，构成了带有水填充的空心介电微胶囊和吸光聚合物壳的理论研究。通过FDTD和FEM技术，进行了微胶囊内部和附近的光场空间分布的数值计算，以及各种形态类型（球形，椭圆形，椭圆形，盒，盒子，立方体，cy，cylinders和Microcapsaples clusers cluserations cormedecters in Aldent Enformionters）的核心壳微粒的温度概况的时间动态。光吸收区域的空间构型显着取决于微胶囊的形态。对于分离的微胶囊，最有效的激光加热是在立方和圆柱形形状的胶囊中实现的。当将胶囊聚集到密集的堆积簇中时，对于圆柱微胶囊，整个组件的特征加热深度更高。在稀疏的微型材料中，方形胶囊优于提高激光加热的效率。
The theoretical study of laser-induced heating of a transport cargo microcontainer constituting a hollow dielectric microcapsule with water filling and a light absorbing polymer shell is presented. By means of FDTD and FEM techniques, the numerical calculations of optical field spatial distribution inside and near the microcapsules are carried out, and the temporal dynamics of temperature profiles of core-shell microparticles of various morphological types (spheres, ellipsoids, boxes, cubes, cylinders) and microcapsule clusters in different configurations is addressed. The spatial configurations of light absorption regions are shown to be substantially dependent on the morphology of the microcapsules. For isolated microcapsules, the most efficient laser heating is realized in capsules of cubic and cylindrical shapes. When the capsules are aggregated into the densely packed cluster, the characteristic heating depth of the whole assembly is higher for cylindrical microcapsules. In sparse microassemblies the square-shaped capsules are preferable for increasing the efficiency of laser heating.
