Abstract: view of the question of big workload and complicated procedures when designing electrostatic detecting electrodes with the method of ANSYS simulation, it introduces a simulation method using Maxwell software of electromagnetic field.  With Maxwell software, the mathematic model for the detecting system was built, based on the theory of electrode designing. With the optimized parameters, a distributed nephogram of inductive electric field on electrodes was formed. Simulation results were obtained from the visual contrast of the color list. The results show different values of the electric field energy with corresponding colors. The test results indicate the simulation results with Maxwell software are effective, the capability of the detection system is improved, and that the method is easier to adopt.
