摘要

Stacked chassis has wide application in aerospace integrated electronic systems. However, with irregular enclosure structure and multi-module integrated into small space, its electromagnetic shielding effectiveness (SE) prediction is a challenge problem. In this paper, a novel method of SE prediction for stacked chassis is proposed based on snow-ablation optimizer (SAO) algorithm. First, a dedicated model of stacked chassis is selected and the SE at five internal sampling points is obtained via full-wave numerical simulation. Then, building on the Robinson equivalent model combined with the generalized Baum-Liu-Tesche (BLT) equations, and exploiting the initial simulation data as priors, the characteristic parameters of the stacked chassis are achieved via the SAO algorithm. On this basis and under vertically polarized and normally incident plane wave, the SE is predicted at all the positions across the central axis normal to the incident face of the chassis. The prediction results enable identification of the optimal SE distribution along frequency axis inside the chassis, thereby informing the internal layout and placement of sensitive devices. The prediction curves agree well with the simulation results, which can overcome the large-error limitations of conventional analytical approaches for complex cavities.
