It is Ensemble. While the total phase is near 1%, when one unwraps the
phase,
or looks at the dispersion, one sees clearly that they have a definite
problem.
Simply simulate a Schiffman phase shifter. The phase should have a
relationship
of angle+sin(angle) vs frequency. They have a second order effect
showing.
I would be more than happy to show you measured results, Ensemble
results,
and results of other 2D modelers.
