"A behavioral model is introduced, which can predict low-loss and low surface roughness transmission line time- and frequency- domain performances. High data rates push for better performance of PCB transmission lines. However, the roughness of copper foil has a considerable impact on the signal integrity performance of transmission lines at high data rates and long propagation distance. Existing models for low-loss transmission line surface roughness are inadequate. A new behavioral model to represent the surface roughness has been developed. The model is applied in the design process by adding a dispersive term to the bulk dielectric permittivity to represent the loss due to the foil surface roughness. By adding a broadband dielectric model into original transmission model, time- and frequency-domain performance improvements is achieved.
Two version of high-speed PCB test board via-transition design optimization is presented, the goal is to make the working frequency up to 50GHz and also will summarize a design flow for design a high-speed board with single and differential signal traces"--Abstract, page iii.
