In this study, the capacitances of arbitrary-shaped conducting surfaces are evaluated based on the Characteristic Basis Functions method (CBF) in conjunction with the Integral Equation Method (IEM). In this method, the surface of the conducting body is divided into a small number of blocks and the IEM with pulse basis function and point matching technique is employed to calculate the charge distribution on the surface of each block. The charge distributions on each block constitute the high-level basis functions of characteristic basis function method. The IEM is then applied to the conductors using the obtained CBF as a basis function for the blocks. The use of CBF results in a highly accurate solutions with significant savings in computation time and memory requirements.]]>Al-Sabayleh, M.A.,2008Ardon, V., J. Aime, O. Chadebec, E. Clavel and E.
