** Shielding Effectiveness (SE) at 1 -50MHz : measured using IEC 6233-2 Rde Inter Decoupling Ratio method  (loop to loop distance= 6mm).
This method is meaningful as a measure of decoupling effectiveness circuit to circuit or to metal surfaces (plane to plane).
*** Shielding Effectiveness (SE) at 100MHz+ : measured using IEC 6233-2 Rrs Radiation Suppression Ratio method  (50-ohm Microstripline).
This method is meaningful as a measure of shielding for radiated emissions of “antennas”.
