Analytical solutions of surface potential distribution on thin insulators having grounded backing conductor and their applications to electrostatic characterisation

摘要

Analytical solutions for surface potential on thin insulators having a grounded backing conductor are obtained by using the model of a distributed resistor-capacitor network. In this paper, we present the steady-state and transient solutions for disk and rectangular thin insulators, and apply the solutions to determine the resistance path to ground and charge relaxation.
