摘要:
 提出一种包含误差补偿项的任意折线线圈阻抗解析新模型。首先,在前人研究的基础上,通过定义外形位置因子,简化单矩形折线线圈的阻抗计算。其次,对多个单矩形折线线圈之间的相交耦合作用进行研究,建立串联等效电感模型。再次,讨论任意形状折线线圈的拆解和重构过程,研究重构过程的误差分布,并推导出误差补偿的数学表达; 进而得到任意形状折线线圈的入射场阻抗及散射场阻抗的完整解析模型。最后,对螺线形折线线圈这一典型特例进行计算,绘制阻抗平面图,并利用高精度阻抗测试仪进行物理验证实验。结果表明,所提方法能有效补偿线宽因素带来的误差,可对置于导体上方的具有不同激励频率和提离的任意形状折线线圈的阻抗进行解析计算。
Abstract:
 An impedance analytical model of arbitrary shape meander coil is proposed in this paper. First-ly,the impedance calculation of single rectangular meander coil was simplified by defining shape-positionfactor. Secondly,the coupled effect between several overlapped meander coils was studied and the seriesequivalent inductance model of which was established. Thirdly,the separation and reconstitution proces-ses of arbitrary shape meander coil were discussed,
and the math expressions of error compensation in re-constitution process were also derived. Furthermore,the completely analytical model of incident field andscattered field impedance for arbitrary shape meander coil was obtained. Finally,a case of meander spiralcoil was analyzed,and a series of physical verification experiments were carried out with a precise imped-ance tester. The results demonstrate that the presented method can be used in impedance analytical calcu-lation of arbitrary shape meander coil,and placed over the conductor in different heights with differentexcitation frequencies.
