A review of the perturbation theory to calculate the wave propagation constant for a waveguide containing a plasma cylinder of small radius on its axis is presented. The wave propagation constant is important for implementing some diagnostic techniques. In the present paper, this constant for a column of a cold, magnetoactive plasma of small radius is calculated, assuming that the distribution of electron density in the plasma is a parabolic function of the radius, and it is shown that this result simplifies the determination of the average plasma density. Moreover, it is shown that for the particular case of an H{sub 11} mode, the result obtained at the electron cyclotron resonance, can be used to gauge the waveguide as well as to describe a simplified model of the plasma heating in an electron cyclotron resonance plasma source. {copyright} {ital 1997 American Institute of Physics.}
