 Abstract

With the aid of the analytical formulas of the disc pair model inter-shielded by different type of shield wires, the total series capacitance of the disc pair could be calculated. After introducing a number of inter-shield pairs to the disc pair model, the influence on the mutual inductance between discs has been thoroughly discussed. Last but no least, after comparing the figures for the voltage response distribution among different configurations and different type of inter-shield pairs, the case which could contribute to the best voltage response performance is selected.
