摘要
电容器一般视为不计板厚的理想元件,但实际上板厚对其电场分布存在着较大的影响.利用施瓦兹-克利斯多菲变换得到忽略板厚时平板电容器的边缘场强分布,再利用有限元模拟得到计及板厚时平板电容器的边缘场强分布.通过比较与分析,得出了边缘场强随板厚的变化关系以及边缘定点处的场强理想值误差.
The capacitor is generally regarded as the ideal element regardless of its thickness,but,it actually has a great influence on the electric field. This article gets the distribution of edge electric field ignoring the plate thickness by taking advantage of Schwarz ﹣ Christoffel transformation. As for the different thicknesses of the capac-itor,the distribution of edge electric field can be obtained by the use of the finite element simulation. We can ob-tain that the changes in relations between plate thickness and electric field,as well as the errors of the ideal value in point through comparison and analysis.
