摘要
Abstract
This gaper reports a related microwave diagnostic method that measures both the electron number density and the electron-neutral collision frequency,which are crucial to understand the behavior of microwave traveling in plasma.Arrays of standard commerci fluorescent lamp placed directly against each other in two rows are used to peoduce a plasma layer.Attenuations of microwave by plasma layer are studied experimentally in the frequencies of 1～8 GHz using a synthesized signal generator and a spectrum analyzer.Two wave-polarizations are under investigation:electric field of the wave is either parallel(E-wave)or perprndicular(H-wave)to the fluorescent lamp axis.The electron number density and the electron-neutral collision frequensy of fluorescent lamp plasma are obtained by microwave diagnstics,for the purpose of analyzing microwave scattering characteristics by plasma.关键词
