And thus we can use the known potential at the
electrode interface to derive two sets of equations due to the two dielectrics
used. The first set of three equations based upon the three or nE contour points
takes only dielectric I into account, for which the charges within dielectric II
can be neglected Using eqns (4.80) and (4.81) subject to two new boundary conditions, the
electric field within dielectric II could be computed, as all Qj charges within
eqn (4.87a) which are not yet known define the potentials within this material
