The electric fields in the polar cap region of the magnetosphere of a pairless orthogonal rotator are being calculated using a modified Poisson's equation which takes explicit account of the effect of the displacement current on the potential Φ. This is the first step in a program to determine how return currents are formed in these models and the resulting global current flow patterns. The potential is being calculated from 0.1 RL to 3 RL, where RL is the light cylinder radius, using known results for ⊘ at 0.1 RL with an inner last closed magnetic field line corresponding to that of a point dipole. Considerable difficulty is being encountered because of the mixed nature of the equation and the irregular boundaries. Possible methods of overcoming these difficulties are indicated.
