Hello,
guess ADS is a possible tool.
As far I remember Agilent updated the modelling of surface roughness in
ADS2011
I did a short search on the Agilent website regarding surface roughness:
http://www.home.agilent.com/agilent/facet.jspx?cc=DE&lc=ger&k=surface+roughness&sm=g
There have been some hits on papers to this topic ..
Best regards
Hermann
