(a) The electric dipole model taking into account boundary conditions BC1 and BC2 (for one electrode and x0 = 0). (b) The method of images—intuitive explanation of consecutive reflections/images and their relationship with boundary conditions BC1 and BC2 (1—first step, 2—second step, 3—third step, 4—fourth step). (c) The electric dipole model taking into account boundary condition BC3 (for one electrode and x0 = 0). (d) The method of images—intuitive explanation of consecutive reflections/images and their relationship with boundary conditions BC1 and BC3 (1—first step, 2—second step, 3—third step).
