Some observations about shielding extremely low-frequency magnetic fields by finite width shields

RG Olsen, P Moreno - IEEE transactions on electromagnetic …, 1996 - ieeexplore.ieee.org
Shielding of extremely low-frequency magnetic fields is limited by fields penetrating through
imperfect material and leakage around the edges of shields which do not completely
enclose the shielded region. The latter effect, more specifically the effect of source geometry
and shield type on leakage, is the subject of this work. Particular attention is paid to
elementary cylindrical dipole sources since the dominant fields of complex two-dimensional
(2-D) sources can be represented as those of dipole sources. When possible, insight is …
