Dear YuanChen,
the geometry you defined has layers as thin as 0.05 MICRONS. The models
of the code cannot be used for such thin layers. A minimum size of about
1 micron should be kept to get meaningful results. For micron-sized
geometries, single scattering should be set for all steps (see note 5 to
the mulsopt description in the manual)
Greetings
Paola
