On the Impedance Method for Measuring High Electron Density and Electron Collision Frequency in a Gaseous Plasma Column

摘要

An analysis of a microwave impedance method for measuring electron density and effective electron collision frequency in a plasma column is reviewed. It is evident from laboratory observations that surface polarization effects may be present in the impedance method. Such a consideration alters the form of the usual expression for the complex dielectric constant of an ionized gas. (Author)
