Abstract: We present the approach that unifies the analytical description and a new model of the cylindrical plasma produced and sustained by а weakly damped surface-wave. This approach includes the use of a fixed-point magnetic-current model. An analytical expression is reported for the normalized power of a surface plasma wave, Q˜. This power is determined as a function of the normalized wavenumber X. We show that the absorbance of the power has a clear maximum at around X∼3 – for the parameters used; the magnitude of the maximum depends on dielectric losses such that Q˜ generally increases with the increase of tgδ. Analysis of the formula for normalized power of surface electron plasma wave has shown the necessity for evaluating the dispersion relation. Since this equation is very complex and implicit, the calculations are not clearly seen. In this paper, an attempt has been made in order to overcome the difficulties, by applying the fixed convergent iteration algorithm. We show in this paper that the fixed-point method is efficient and can be adapted for computations performed here.
