We consider here the special case where rho = 0, to model a conducting
microstrip line on top of a dielectric substrate. A Dirichlet boundary
condition sets the potential to 1 mV on the boundary of the line (called
"Electrode" below) and 0 V on the ground. A homogeneous Neumann boundary
condition (zero flux of the displacement field, i.e. n.d = 0) is imposed on a
surface truncating the modelling domain. */

imposed on the left boundary of the domain to account for the symmetry of the
problem, as well as on the top and right boundaries that truncate the
