摘要
利用单磁偶极子辐射场的矢势推导出双磁偶极子和阵列磁偶极子辐射场的一般形式,并对阵列磁偶极子辐射场的相干特性进行了分析,结果表明阵列磁偶极子辐射场具有很强的方向性,在干涉因子取极大值的方位上可接收到很强的电磁信号。
When the double or array magnetic dipoles are put in the conductive media, the formula of radiant field of them are derived from vector potential equation of single magnetic dipole. The interferential characteristics of radiant field of array magnetic dipoles are discussed in detail. From the result, we see that the radiant field exists directionally. In the directions, where the interferential factor gets maximum, the strongest electromagnetic signal can be obtained by choosing the azimuth.
