| 摘 要： | 从电磁媒质的本构关系出发,给出了线性电磁媒质的分类,详细讨论了包括各向同性、各向同性双负、双各向同性、各向异性、双各向异性等媒质的特征及其本构关系;论述了媒质的互易特性,分析了新型电磁媒质特别是各向同性双负媒质和双各向异性媒质中尚未完善的一些基本概念或有待于研究的问题。对新型电磁媒质的制备、电磁媒质参数反演等研究提供了必要的理论归纳和准备。 |
| 关 键 词： | 电磁媒质 特征分类 本构关系 双负媒质 双各向异性媒质 互易性 |

| Abstract: | With new artificial composite materials made, some new terms of electromagnetic media have appeared. It is necessary to summarize the classification methods of the EM media. According to the constitutive relationship of EM media, the classification of linear EM media is discussed. The characteristics and constitutive relationship of various media, such as isotropic, double negative, bi-isotropic, anisotropic and bianisotropic media, are given. The reciprocity of the media is also mentioned. Some un-clarified basic concepts and unsolved problems for some new EM media are provided. This work provides essential theoretical summary and preparations for further research on new media preparation, media parameter reconstruction and so on. |
| Keywords: | electromagnetic media characteristic classification constitutive relationships double negative media bianisotropic media reciprocity |
