Hi folks,
I would like to know if there is any study out there which explains the
correlation between surface roughness and loss at higher frequencies.
Trying to match the S-parameter from VNA measurements with simulated
measurements and I believe playing around with surface roughness should
help me narrow the gap between the two.
If there are papers/articles out there which explain how to best model
surface roughness without have to do the actual cross section of the board,
that will be great.
