Abstract

Introduction. In order to reduce the field inhomogeneity caused by edge effects and ca-pacitance of two parallel metal plate electrode system we have proposed a mathematical model of conductive multilectrode cylindrical system.
Analytical analysis techniques. According to the model the analysis of the distribution of the electric field inside the zone restricted with multiply connected circular boundary on the basis of the theory of singular integral equations in the form of conjugation problem is per-formed. The calculation of the electric field distribution is reduced to the consideration of partial problem where only one electrode possesses a non-zero voltage. It is shown that pro-viding the harmonic feeding of the electrode system consisting of identically sized equally spaced arc-shaped electrodes with voltages of the same amplitudes and phases equal to the angular position of the electrode on the circle will ensure the feasibility of the rotating and homogeneous field in the area. The expressions for determination of the electric field strength in the area are given.
Results and discussion. It is shown that the size of the field homogeneity zone depends on the number of electrodes in such a way that increasing the number of elements causes the in-creasing of the zone size, and with the number of electrodes equal to 8 the diameter of the zone is equal to 60% of structure. It is proved that such an electrode system can be success-fully applied for creating of apparatus for bulk materials irradiation. A schematic diagram of a generator for the electrodes supply and the principle of building of the apparatus for treat-ment of grain and other bulk materials with the electric field of high frequency are proposed.
