Electronics shields

Electromagnetic compatibility (EMC); Compatibilité électromagnétique (CEM)

The EMC of any electrical or electronic equipment, must satisfy two compliances, firstly, under a specified level of interference, its operating cycle must be achieved without fault, secondly, its own operating, must don’t produce spurious interferences in its vicinity area.

Plane wave; Onde plane

Normally, amplitude of a plane wave, doesn’t change in any plane perpendicular to the propagation direction. In practice, this condition is only true in a small area around the propagation axis.

Transfer impedance (Z_t); Impédance de transfert (Z_t)

Transfer impedance parameter, is used to characterize the shielding efficiency of a shielded cable (or connector), in terms of ratio between the resulting voltage as appears inside,...
