Hi all, I have developed a new way of calculating skin effect, and dielectric losses in the time domain and would really like to try and validate the model / my theories. Please does anybody have some loss Vs frequency data for a single, copper only stripline or microstrip in FR4 / rogers preferably recorded with a VNA? I am not after lengths of backplane dimensions, anything around 3-5 inches would be great. If anybody could mail me this data with the trace dimensions (width, thichkness, width of dielectric to the ground, type of materials etc) I will happily mention any assistance in my research write ups / papers / conferences I submit to.
