Simplified algorithm of electrostatic fields analysis

Summary form only given. An algorithm of electrostatic field analysis formed by complex configuration electrode system is considered. The algorithm is based on Fourier transformation of electrode profile. The function of electrode profile is smoothed out with help of a low-pass filter to produce equipotential line. In dependence of distance between the equipotential line and the electrode the frequency response of low-pass filter is changed . Reducing of cut-off frequency of filter corresponds to increasing of distance. With the help of the proposed algorithm to obtain equipotential line for electrostatic systems with electrode profiles, description by unambiguous functions easily succeeds. Typical examples are different inserts into waveguides and strip transmission lines.
