摘要：

A transmission line method is presented for measuring the shielding effectiveness of conductive composite materials. It is shown that the transmission line method give data similar to free space measurements and if the specimens are electrically ″thin″ the SE is flat across the frequency band. Data also show measured resistivity of specimens. It is concluded that: the transmission line method should be used as a standard to measure the intrinsic SE of conductive composites; the method is simple and would give uniform results among investigators in contrast to measurements more commonly mode in shielded boxes.
