In this paper, cylindrical plasma was generated steadily in a cylindrical cavity by high-frequency AC discharge, and some cylindrical plasma were layered directly against each other to form a plasma layer. The cylindrical plasma layer's effect on microwave transmission attenuation was measured by the vector network microwave measurement system in the frequency range 2~18GHz experimentally. The factor, such as wave polarizations, electron densities and the number of layers were analyzed. In the set of the experiments, cylindrical plasma layer was more effective to VP wave than HP wave. And this layer was effective in the frequency range 2~10GHz; in this band, the attenuation can be adjusted uniformly by changing the electron densities. The double cylindrical plasma layers were more effective than the single one.
