Yes, if I am not mistaken, MOM assumes that the radiation
from each segment is proportional to the net current in
the segment. The maximum radiation comes from the segment
in which the forward and reflected currents are in phase.
The minimum radiation comes from the segment in which the
forward and reflected currents are out of phase.
