Abstract :
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.
