Capacitance and charge distribution of two cylindrical conductors of finite length

摘要

The authors present a method of finding the effect of fringing on capacitance and charge distribution of conducting structures consisting of coaxial cylinders or of parallel cylinders of identical diameter, each of finite and equal length. The moment method, employing pulse and delta functions as the basis and testing functions, respectively, is used for the analysis. Numerical data on charge distribution and capacitance per unit length, normalised to the same quantity for similar structure of infinite length, are presented.
