Capacitance computation of arbitrarily shaped conducting bodies by spacecraft surface charging analysis

摘要

This paper presents numerical estimation for the capacitance of an arbitrarily shaped conducting bodies based on the moment method with triangular patch modeling. The integral equation is evaluated numerically using a Gaussian quadrature method for triangles. The singular elements of the moment matrix are evaluated by using the Duffy transformation method. The Numerical data on the capacitance of conducting objects such as cuboid is presented. The computed results are compared with the previously published results. The findings of our study show that the Method of Moments is a more accurate method for the computation of free space capacitance.
