Abstract
The plane medium and point charge are regarded as an integral system. The static field's distribution situation of the point charge is studied in the medium structure of plane division layers by using mirror image method, drawing the point charge's calculation expression of the electric potential in every medium space. The mathematics model of passive electrostatic detecting people through the medium (regular distance between the goal point charge and the medium) is established, using MATLAB software to carry out emulation of the model and analysing the result, establishing the theoretical foundation for studying the technology of the passive static detecting people through the wall.
