电磁学中媒质介电性的分析与探讨

Analysis and Discussion on Dielectric Property of Medium in Electromagnetics

众所周知,电磁场与电磁波理论的深入理解是非专业人员难于做到的。而对于媒质的介电性和电导性关系,现有专业书籍更是涉猎甚微。根据这一实际情况,有针对性地展开了分析和探讨。首先分析了静态场和动态场中媒质的介电性,然后对静态场和动态场中媒质的介电常数和电导率进行了分析和探讨,最后分析了良导电媒质(金属)的介电常数。希望能够有助于电子工程师对相关问题的深入理解,并提供有价值的参考。

As is known to all,it is difficult for non-professionals to have a deep understanding of electromagnetic field and wave theory.There are few professional books about the relationship between dielectricity and conductivity of media.According to the present situation,this paper analyzes and discusses it.In this paper,the dielectric properties of medium in static field and dynamic field are analyzed firstly,then the dielectricity and conductivity of medium in static field and dynamic field are analyzed and discussed,finally the dielectric parameter of good conducting medium(metal)is analyzed.It is hoped that this paper can help electronic engineers to have a deep understanding of related issues and provide valuable reference.
