I have to use the opportunity to plug SuperNEC which will give better
results than NEC-BSC since it incorporates an impedance matrix
MoM-GTD/UTD hybrid, i.e., the antenna (dipole) impedance will be
modified by the plate (MoM interaction matrix includes all GTD/UTD
diffraction/reflection paths. With NEC-BSC the MoM currents are used
as sources to the GTD model without considering changes in the MoM
currents as result of interaction with the GTD objects. See
