High temperature thermal energy surface coatings have been developed to achieve advanced thermal managing system. The key concept of the coating is to apply interference effect of electromagnetic wave using oxide ceramic multi layer structure. Application of the interference effect to thermal energy control needs (1) wide wavelength interference design and (2) high reflection over wide incident angle of electromagnetic wave. To solve these problems, three-dimensional wavy surface morphology is employed for design of the coatings. To design three-dimensional wavy surface, simulation is used : the procedure is evaluated to compare model results with experimental ones. Simulation results demonstrate the effectiveness of the wavy surface layer on thermal energy reflection. The maximum possible reflectance estimated from this simulation is larger than the flat surface. It is concluded that the present thermal energy control surface is effective way to control thermal reflection energy at high temperatures.

为了实现先进的热管理系统，人们开发了高温热能表面涂层。该涂层的核心概念是利用氧化物陶瓷多层结构来应用电磁波的干扰效应。将干涉效应应用于热能控制需要(1)宽波长干涉设计和(2)电磁波大入射角高反射。为了解决这些问题，采用了三维波纹表面形态来设计涂层。对于三维波浪面的设计，采用了模拟的方法：对程序进行了评估，将模型结果与实验结果进行了比较。仿真结果验证了波状表层对热能反射的有效性。通过此模拟估计的最大可能反射率大于平坦表面。结果表明，现有的热能控制面是控制高温下热反射能的有效途径。
