| | Calculates the number of grid points the given index is pass the domain boundary i.e. a value of +1 means the current cell is outside of the simulation domain by 1 cell. Note that the high side domain boundary is between cell dom_hi and dom_hi+1 for cell centered grids and on cell dom_hi+1 for nodal grid. This is why (dom_hi[idim] + is_nodal[idim]) is used below.

| | Sets the electric field value tangential to the PEC boundary to zero. The tangential Efield components in the guard cells outside the domain boundary are set equal and opposite to the field in the valid cells at their mirrored locations. The normal Efield components in the guard cells are set equal to the field in the valid cells at their mirrored locations. The number or depth of guard cells updated is equal to the shape factor of particles in each dimension. For corner cells with mixed boundaries, the mirror location could be outside valid region, while still ensuring PEC condition is maintained across the PEC boundary, and the necessary sign change is accounted for depending on if the component, icomp, is tangential or normal to the PEC boundary.

| | Sets the rho or J field value in cells close to and on a PEC boundary. The charge/current density deposited in the guard cells are either reflected back into the simulation domain (if a reflecting particle boundary is used), or the opposite charge/current density is deposited back in the domain to capture the effect of an image charge. The charge/current density on the PEC boundary is set to 0 while values in the guard cells are set equal (and opposite) to their mirror location inside the domain - representing image charges - in the normal (tangential) direction.
