Differences between NSA 94-106 and IEEE Std. 299 Setups for Low-Frequency Magnetic Shielding Effectiveness Characterization: A Study Using Numerical Simulations KU Leuven
This letter employs simulation findings to demonstrate the practical reasons why the low-frequency magnetic shielding effectiveness is different when characterized using two parallel loops (NSA 94-106) or two coplanar loops (IEEE Std. 299). It is shown how the change in the loop’s radius impacts the shielding effectiveness for the NSA 94-106 setup rather than for the IEEE 299 one. The observation is rooted in the difference of the wave impedance ...
