Application Boundary Element Approach to Compute the Electric Field Intensity of the Thirteen-Needle Electrodes in Vacuum

Abstract

According to the electric field intensity of thirteen-needle electrodes in vacuum, the discrete equations based on the indetermination linear current density were established by the boundary element integral equations. The non-uniform distribution of the current flowing from thirteen-needle electrodes to conductive in vacuum was imaged by solving a set of linear equations. Then, the electric field intensity generated by thirteen-needle electrodes in vacuum at any point can be determined through the boundary element method. It means that this method has an important referenced significance for computing the electric field intensity generated by thirteen-needle electrodes in vacuum
