磁耦合问题的定量分析涉及到导体自感、导体间互感、电感耦合系数等的计算，是沿着整个电磁学发展史上一个备受关注的问题。以前，计算必须进行三维EDA求解器的帮助下，通过离散化的整个体积。这是相当繁琐和计算昂贵的。工程师可能需要一种简单的方法来估计电感值，而无需任何复杂的计算工具。在本文中，我们提出了一种新的方法来完成这一任务的基础上部分电感理论。给出了一个计算两个磁谐振线圈耦合系数的实例。
Quantitative analysis of magnetic coupling problems involves the calculations of self inductance of conductors, mutual inductance between conductors, and inductive coupling coefficient etc. It is an issue of great interest along the whole electromagnetics evolvement history. Formerly, the calculations have to be carried out with the aid of three-dimentional EDA solvers by discretization of the entire volume. This is rather tedious and computationally expensive. Engineers may need a simple approach to estimate the inductance values without any complex computational tools. In this paper, we propose a new method to fulfill this task based on partial inductance theory. An example with the procedure to calculate coupling coefficient of two magnetic resonant coils is presented.
