“…The stability and environmental adaptability of the VPX chassis under plane wave radiation need to be further verified. It is a prerequisite and a necessary requirement to analyze the electromagnetic environmental effects of the VPX chassis and propose protective measures in order for the chassis and its internal electronic equipment to work normally in complex electromagnetic environments [15][16][17][18][19][20]. However, in the existing literature, the electromagnetic environment effect of the VPX chassis has not been well investigated, whether with theoretical calculation or simulation methods.…”

The chassis based on the VPX bus standard structure has been widely applied to the fields of vehicle, missile, radar, etc. In this paper, we analyze the electromagnetic environment effect on VPX chassis via the CST software, and investigate the electromagnetic coupling characteristics of VPX chassis under 20 v/m plane wave radiation according to the RS103 test defined in the MIL-STD-461G standard. By simulation, we analyze the electromagnetic coupling paths of the VPX chassis, find the key positions of the electromagnetic protection such as the air intake, air outlet, trapdoor, and panel gaps, and we propose the electromagnetic protective measures for the weak parts of the VPX chassis. The electromagnetic shielding effectiveness before and after protection design is evaluated. Finally, the simulation results are verified by the experiments. It has guiding significance for the electromagnetic protection design of VPX chassis.

“…The primary goal in all conformal shielding design is to improve the SE. While an amount of the existing literature focused on the influence of shielding layer material and shielding layer thickness on SE [2,3,4,5,6,7,8,9,10,11,12]. There were also a number of studies on SE measurement methods in [13,14,15,16,17] and probe calibration in [18,19,20,21].…”

Conformal shielding, as an efficient method for solving the electromagnetic interference (EMI) problem, is becoming increasingly important. In this Letter, the Taguchi method in quality engineering was introduced into the design optimization of conformal shielding. As a pilot test, the authors studied the order of the effects of shielding layer material, shielding layer thickness, and distance between ground vias (D-via) on shielding effectiveness (SE). The comparison between simulated results and predicted results proves that the optimization method is accurate and effective. The thin-film conductivity of copper was measured, and the model was revised using the measurement results. For validation, built a near-field scanning platform, and measured shielding effectiveness and simulated shielding effectiveness show a good agreement from 0.1 to 7.5 GHz.
