I'm not sure I understand the question, but a large fraction of the

Roy you know better than that ! gain is a binomial function with
respect
to the forward radiation at the point of initiation. It does nothing to
salvalge energy
expended in the reaward direction, to do that another vector is
required that cannot be produced by a planar array.

Sorry, I can't make the slightest amount of sense out of this.

As far as traps
being lossy as if they get hot or something that is also untrue, what
you are seeing is a radiation field created by the trap that is in
opposition to that created on the element i.e. a field that is 180
degrees out of phase

Egad. There's no point in my wasting time by attempting to contribute
further to this. I'll leave you to your alternate reality.
