点配法的改进

Enhanced point-match method

针对点配法求解精度低的问题,提出了一种改进方法,改进的点配法有较高的精度,使用该方法可以计算天线电流的导数分布。改进的点配法能以较高的精度求解第一、第二、第三类Fredholm积分方程。修正中波天线模型,按照模型可以精确求解天线输入阻抗。

An enhanced point-match method is presented to improve the precision of solving EM problem. As a practical application, this new method is used to modify the LF antenna model, calculate the current distribution and the input impedance of the antenna. Theoretically, the presented method can be widely used in solving the first, second and third order Fredholm integral equation in a better precision.
