Table 1 Relation between SET and the percentage of incident EM wave blocked by the shield material
From: The journey of polycarbonate-based composites towards suppressing electromagnetic radiation
SET value (in dB) | − 10 | −20 | −30 | −40 | − 50 | −60 | −70 |
|---|---|---|---|---|---|---|---|
Transmitted power \( {P}_T=\frac{P_I}{10^{\left(\frac{SE_T}{-10}\right)}} \) | 10−1 PI | 10−2 PI | 10−3 PI | 10−4 PI | 10−5 PI | 10−6 PI | 10−7 PI |
% Shielded power \( \%{P}_S=\frac{\left({P}_I-{P}_T\right)}{P_I}\times 100 \) | 90% | 99% | 99.9% | 99.99% | 99.999% | 99.9999% | 99.99999% |
