Abstract
Reduction of transmission loss is a large technical issue in high-speed signal application. However, there are many parameters for transmission loss, such as dielectric properties of insulator, conductivity of conductor, surface roughness of conductor and so on. Further more, the measures to meet for them are also many techniques. By the way, simulation is very convenient to analyze the ideal model with ideal materials and structure. We studied the priority of the parameters for transmission loss by using quality engineering and simulation.
