| 摘 要： | 在经典电动力学框架下对磁各向异性介质中的电磁辐射问题进行研究, 得到了电偶极子在磁各向异性介质中的辐射功率表达式. 当介质为磁各向同性时其结果与文献报道的结果相符合, 验证了推导结果的正确性. 利用本文结果可对电偶极子在磁各向异性介质中的辐射效果做出判断, 而且对于进一步研究磁各向异性介质的电磁特性、更有效地开发利用磁各向异性介质具有实际意义.

| Abstract: | Under the framework of classical electrodynamics, the electromagnetic radiation in magnetic anisotropic medium is studied in the present paper. The radiation power expression for electric dipole in magnetic anisotropic medium is deduced. The obtained expression in isotropic medium accords with that in the literature, and its validity is therefore proved. The radiation effect of electric dipole in magnetic anisotropic medium can be estimated by the obtained results. It has practical significance for further research electromagnetic property in magnetic anisotropic medium and effective development and utilization of magnetic anisotropic medium. |
