Simulation Analysis of One Electronic Equipment
Electromagnetic simulation software FEKO was used to set up the equipment model and plane wave environment.Data showed: when frequency was lower than 50MHz, the corresponding electromagnetic coupling field of the window appeared round distribution (x=13.4),but when frequency was higher than 250MT-1z, the regional border of the window coupling field became more and more fuzzy;When frequency was 50MHz, the back-door seam region appeared strong reaction electric current;when frequency was 650MHz, the body surface of shell around the back door presented strong reaction electric current, and the surface reaction electric current of back door was relatively weak,which reflected the separating effect of the back-door seam ; when frequency was 900MHz,strong electromagnetic coupling area appeared outside the back door, the initial analysis was the transmission function of the equivalent aerial for the window; when frequency was from 250MHz to 900 MHz, the reflection strengthen function to the coupling field around of the package within the equipment got obvious; very obvious resonance phenomenon appeared when frequency was 900MHz.
