Abstract :
The shielding effectiveness to different sized slots in a shielding enclosure is calculated using the FDTD method. It is demonstrated that the resonance of a shielding enclosure´s cavities and slots greatly influences a screened room´s shielding effectiveness. Fast time-varying EMP couples more easily in a shielding cavity with slots.
