Abstract:

A nonuniform transmission line is modeled for multilayer plates and an effective shielding is obtained by matrix theory. Owing to discontinuity of nonuniform transmission line, it is suited for modeling multilayer plates regardless of re-reflection between plates. Matrix presentation can benefit calculation using programming. A general formula applicable to analyze arbitrary multiplayer plates shielding is proposed. Special cases of double and fourfold shield are investigated. The accuracy of this method has been validated by comparison to other analytical methods.

Key words: nonuniform transmission line, shielding effectiveness, network parameter, matrix theory
