Abstract : A fundamental limitation in microwave measurement of plasma parameters is established: It is shown that it is not possible to determine experimentally such plasma parameters as electron temperature, electron density, or collision frequency by means of a microwave system operating at a frequency well below the plasma frequency because the plasma boundary layer exerts a prominent effect on the measurements. A numerical example is given, using published results for argon. (Author)
