摘要

本文提出了一种计算平面螺旋线圈磁场分布的解析模型。在对磁场均匀性要求最高的地方,磁场建模起着至关重要的作用。用该模型对三匝内半径(1mm)的PSC进行了建模。分析结果与实验测量的磁场结果进行了验证。分析建模在MATLAB中进行,而三维FDTD工具计算机仿真技术(CST)进行仿真。

To model magnetic field of RF planar coil for portable NMR applications
In this paper, an analytical model to calculate magnetic field distribution for Planar Spiral Coil (PSC) is proposed. The magnetic field modeling plays a crucial role where magnetic field uniformity is of highest concern. PSC of three turns, inner radius (1mm), is modeled with the proposed model. Analytical results are verified with experimentally measured magnetic field results. Analytical modeling is carried out in MATLAB, whereas 3D FDTD tool Computer Simulation Technology (CST) is used for simulation.
