I am looking for example trasmission line structures with which to test a 2D field solver. This 2D field solver will be open source and hosted on sourceforge probably in about 2 weeks. I am looking for a variety of configurations: - edge differential - single ended - microstrip and stripline - multiple Er in stripline configuration with information on inputs parameters - geometries (of course) - etchback - Er of glass and resin (resin content) - copper thickness - soldermask thickness (and Er) And the results from a known good field solver including: -common mode and differential impedance -common mode and differential effective Er (and delay if available) -effective loss, DC resistance, and DC capacitance per unit length would be great too.
