Research on simulation and analysis of electromagnetic environment of cabinet in cabin

The low-frequency electromagnetic radiation of cabinet has became the main interference source for electromagnetic sensitive system. The feature of interference sources in cabinet was analyzed, and the electric dipole is considered as the equivalent interference source. Then, considering the low-frequency radiation characteristic, the low-frequency MoM is used to simulate the electromagnetic environment of cabinet in cabin. Then the distribution of electromagnetic environment effected by the cabin structure was further analyzed, and some simulated results were presented to show the distributed characteristics of the electric and magnetic field. And the methods adopted in this paper can also be implanted in the analysis of the sensitivity of inner system of the cabinet to interference source.
