摘　　要：复折射率是描述电磁波在介质中传输规律的重要物性参数。由于其不能直接测量,只能通过测量表观辐射特性相关量,再通过反问题的计算方法求得,因此其测量和计算相对复杂。本文整理了复折射率现今最主要的测试技术和计算模型。在测试技术层面,介绍了复折射率多种测量方法的特点及其适用性;在计算模型层面,论述了正问题模型的来源、计算的简化以及适用的测量方法;其次,从反问题模型的角度,对测量复折射率常用的计算模型进行了梳理,分析其计算特点。The complex refractive index is an important physical parameter to describe the propagation of electromagnetic waves in the medium. In this work, the most important measuring technique and calcula- tion model of the complex refractive index is introduced and summarized. In the aspect of testing technol- ogy, we introduce the measuring methods of the correlation quantity, and its the characteristics and suit- able medium during the calculation of complex refractive index. In the aspect of calculation model, first- ly, we discuss in detail the source of the forward problem, the simplified calculation and the applicable measurement method. Then, the inverse problem model is analyzed, and summarized in the characteris- tics of those models.
