摘要: 考虑到边缘效应,采用保角变换先将非平行板电容器的内部电场区域和外部电场区域变换到复平面的上下半平面,然后再继续变换到复平面的上下半平面的矩形区域,这样就可采用理想平板电容器的电容计算式算出原非平行板电容器的电容.

Abstract: Considering the edge effect, the internal electric field area and the external electric field area of non -parallel plate capacitor are transformed to complex plane of the upper and lower half plane with conformal map- ping. Then we transform them to the upper and lower half plane of the rectangular area of the complex plane. So that it can be used ideal plate capacitor of capacitance calculation formula to calculate the original plate capacitor of ca- pacitance.

Key words: edge effects, conformal mapping, elliptic integral
