摘要

一般来说,具有一定边值的电磁问题是由偏微分方程和必要的边界条件组成的。边界元法(边界元法)是用积分公式分析某些电磁问题的有效方法。通过点配置,可以将边界积分方程转化为线性方程。然后用数值方法对线性方程进行求解,最终得到原PDE方程的解。对于线圈之间的完美电导体(PEC),可以利用目标散射的二次磁场来计算导体对接收线圈产生的感应电压。本文用微扰法计算了两个线圈之间的灵敏度分布,结果表明边界元法是计算磁感应问题灵敏度图的有效方法。

Boundary element method for a kind of 3-D PEC magnetic induction problem
In general, the electromagnetic problem with certain boundary value is composed of a partial differential equation (PDE) and essential boundary conditions. BEM (boundary element method) is an effective way to analyze some electromagnetic problems with integral formulations. By point collocation, the boundary integral equation can be transformed into linear equations. Then numerical method is used to solve the linear equations and finally the solution of the original PDE equations can be obtained. For perfect electric conductor (PEC) between coils, the induced voltage of the receiver coil due to the conductor can be calculated using the secondary magnetic field scattered from the target. Here we compute the sensitivity distributions between two coils due to a PEC object using perturbation method, and the results show that BEM is an effective way to calculate sensitivity maps in magnetic induction problems.
