Webb31 maj 2024 · Steel. Apart from aluminium, steel is an alloy that is frequently used for making radio wave and microwave RF shielded enclosures. Shielding devices made from steel also offer magnetic field shielding capability. The attenuation of steel enclosures is not as large as the ones provided by shields made from copper and aluminium. WebbMethod: We used full-wave numerical simulations to investigate how the SNR of an RF receive coil depends on the diameter of the RF shield at ultra-high magnetic field (UHF) strengths (≥7T). Results: Our simulations showed that there is an SNR-optimal RF shield size at UHF strength, whereas at low field the SNR monotonically increases with the …
