摘要

利用时域有限差分法研究了屏蔽效能随狭缝长度、宽度和腔体尺寸的变化规律。结果表明，当缝隙周长达到入射波波长的奇数倍时，会发生缝隙共振，此时的屏蔽效果较差。

Analysis on shielding effectiveness of metallic enclosures with slot

The FDTD method is used to study how shielding effectiveness varies with slot length, width and cavity size. The results show that slot resonance occurs when a slot perimeter reaches odd times of the wavelength of the incident wave and the shielding effectiveness becomes rather poor in such cases.
