| 英文摘要 | In multichannel magnetocardiography (MCG) or magnetoencephalography (MEG) systems based on atomic magnetometers, the stray field derived from the magnetic coils are the main cause of the crosstalk noises. In this article, a novel nested self-shielded biplanar (NSSB) coil constructed by primary and shielded coils is proposed to suppress the stray field. The coil design theory is based on a modified target field method (TFM) after uniting the inner and outer target regions. And to obtain the optimal design parameters, the particle swarm optimization (PSO) algorithm with a dynamic adjusting (DA) strategy is involved. According to the simulation results from the finite element analysis (FEA) method, the NSSB coil has the capacity to reduce the stray field by about 100 times. In addition, the magnetic field noise originated from the magnetic coil itself can be suppressed by more than ten times. An up-scaled test coil of ten times is then manufactured via the printed circuit board (PCB) technology, and the measured results inside and outside the test coil show a high consistency with the simulated ones. Although there is a fivefold reduction of the uniformity performance in the inner target region, this NSSB coil is still promising in miniatured atomic magnetometers. |
