Horn antennas are *best* modeled via NEC-BSC codes and not
the NEC-MOM code. The effect of diffraction by the edges
becomes important for calculating the backlobe and other
far-out sidelobes. The GTD (or its sibling UTD) is the best
for treating such problems.
You may look up the book by Stutzman and Thiele where the
details of modeling such antennas using the UTD (Uniform
Theory of Diffraction) is described.
