Abstract
The plane medium and point charge are regarded as an integral system. The influence of layered plane medium on the electrostatic field of point charge target is investigated, and the position expression of the image charge is given. The charge amount calculation expression of the image charge in three layered mediums is reckoned based on the formula of the image charge in two layered mediums. The physics model of the passive electrostatic detection system in the plane medium is built. The calculation formula of the electric intensity in the space where the detection electrode is placed is given. The method of circumrotate electrode and electrostatic induction principle is used to detect the target. The detection equation of the passive electrostatic detector is confirmed, and the feasibility is proved by simple examination.
