Integral solution of electrostatic fields in 3D arrangements

The paper deals with computation of 3D electrostatic fields (distribution of charges, electric potential and other derived quantities) by means of integral equations and their numerical solution. Selected are neither configurations that can be simplified to 2D problems and solved analytically, nor arrangements that might be processed by the FD or FE techniques. Analysed are fundamental mathematical aspects of the method, which is illustrated on a 3D field between two cubes in a general position
