Abstract The electromagnetic energy leakage through aperture arrays which were often designed for controlling temperature of avionics was inevitable. The near-field shielding effectiveness must be analyzed when the distance between two avionics was short. The calculation of near-field shielding effectiveness by the HFSS and the other one by the transmission line method was compared. Both the theory analysis and numerical results indicated that the transmission line method was noneffective in the calculation of near-field shielding effectiveness. The effects of some parameters on near-field shielding effectiveness were analyzed thoroughly by the HFSS. Some means for improving near-field shielding effectiveness was presented.
