Abstract. The aim of this work is to develop an algorithm and program for calculating the dispersion characteristics of the resonator slow-wave systems with channel -flight filled with plasma, using the methods of three-dimensional modeling. To achieve this goal the following problems were solved:
1. the problem of describing the cell resonator slow-wave system with channel-flight filled with plasma transfer multipole matrix is formed and the ratio for determination the dynamic characteristics of slow-wave systems of the coefficients of the matrix are shown;
2. a review of methods for solving key problems of electrodynamics and programs suitable for determining the coefficients of the transfer matrix multipole modeling cell slow-wave system are given;

3. algorithm and data processing of software simulation of three-dimensional resonator slow-wave system are developed;

4. an analysis of the dispersion characteristics of the resonator slow-wave systems when the concentration of plasma is fulfilled.

Keywords: slow-wave structure, multipole, three-dimensional modeling, electrodynamic characteristics.
