摘要:

We propose a simple method for solving some electrostatic problems normally treated by images. The method is based on the multipole expansion of the electrostatic potential due to both real and image charges. The magnitude and the location of the image charges are found by imposing the proper boundary conditions. Some typical problems with spherical and with spheroidal symmetries are worked out explicitly.
