用于评估圆柱形系统中屏蔽效能的上限频率测量边界

This AIR points out that above a frequency called the “transition frequency,” variances associated with the shielding effectiveness measurements can become large. It includes the derivations to demonstrate this. This fact should be taken into account when designing shielding for use above the transition frequency.Cross Reference: MIL-C-38999H,MIL-C-39012B,MIL-STD-1344A
