Reply To: How to do ‘Phase Wrapping’?

I believe the result is correct with your simulation settings. Phase is very sensitive to mesh accuracy (and PML reflection). you may need to refine the mesh with proper total PML thickness say half wavelength (number of PML layers times the mesh size in front of PML).

Duplicating other's work is very challenge, since the pulication does not give full details of their material data (even though they say it is a specific material, say Si), and mesh size. Please refer to this post: 

Ansys Insight: Why my simulation result is different from published paper or experiment?

As can be seen from the the above plots, your simulation result differs from the publication not only in magnitude, but also the shape of the curve. There must be something that differs yours from publication.
