Calculation of the capacitance for a non-parallel plate capacitor

  • Online:2014-07-25 Published:2014-07-20

摘要: 在计算非平行板电容器的电场和电容时,以往文献大多忽略分布在电容器外部的电荷.本文将电容器外部电荷纳入计算过程,用三种方法得到更加准确的非平行板电容器电容,较其他文献新增了修正项.

关键词: 非平行板电容器, 拉普拉斯方程, 高斯公式, 边界条件, 能量法

Abstract: Previously,most of the literatures have ignored the external electric field of capacitor in the calculation of non -parallel plate capacitor and capacitor electric field. In the present work, we investigate the external electric field of capacitor and apply three methods to get more accurate results with correction term.

Key words: non-parallel plate capacitor, Laplasse equation, Gauss formula, boundary condition, energy method
