提出了一种新的屏蔽效能的整体描述，该描述考虑了金属外壳中的总能量存储，以取代现有的一些定义在一个特定点上的屏蔽效能描述，如频域屏蔽效能和时域屏蔽效能。电场和磁场被认为是全球在这个新的描述，并根据这个新的描述与不同的瞬态脉冲的数值计算可以得到。对脉冲激励的圆孔矩形腔进行了数值模拟，结果表明了本文描述的有效性。
A new global description of shielding effectiveness is proposed in consideration of total energy storage in a metal enclosure, in order to replace some existing descriptions defined on one specific point, such as frequency domain shielding effectiveness and time domain shielding effectiveness. Electric fields and magnetic fields are considered globally in this new description, and numerical evaluation according to this new description with different transient pulses can be obtained. Simu- lation performed on a rectangular cavity having a circular aperture excited by the pulses is provided to show the validity of our proposed description.
