The uniform and simple solutions of the deflection field distribution of two kinds of multi-polar electrostatic deflectors are deduced. By using the finite difference method, the parameters of the multi-polar static polarizer such as the Fourier transform coefficient and the electric field intensity distribution are calculated , An approximate formula of electric field intensity distribution of multipolar electrostatic deflector and parallel plate electrostatic deflector is proposed. Various characteristics of deflection field distribution of multipolar electrostatic deflector are discussed.
