【摘要】：极化与电磁波另外的两个特性——振幅和相位,在传递信息时具有同等重要的作用,描述电磁波极化及其演化特征具有重要意义.关于电磁波的极化描述,前人针对不同边界条件和初始状态,发展了不同的参数组,但是这些参数组没有全面考虑电磁波的初相.鉴于此,全面考虑了电磁波的初相问题,对极化椭圆参数组的旋向参数也进行了扩充和完善,重新定义了这些参数组,在此基础上推导出这些参数组的相互变换关系,并借助符号数学数值与仿真计算验证了这些相互变换关系的正确性结果表明这些全面包含初相的电磁波完全极化参数组是完备的,相互之间具有一一对应的关系.给出的参数组变换关系显著地简化了繁杂的电磁波极化计算过程,为电磁波极化理论和应用设计提供了更加完备、适用的方案,具有理论参考和应用价值.
[Abstract]:The other two characteristics of polarization and electromagnetic wave, amplitude and phase, play an equally important role in the transmission of information. It is of great significance to describe the polarization of electromagnetic wave and its evolution characteristics.Regarding the polarization description of electromagnetic waves, different parameter groups have been developed for different boundary conditions and initial states, but these parameter groups do not consider the initial phase of electromagnetic waves.In view of this, the initial phase problem of electromagnetic wave is comprehensively considered, and the rotational parameters of the polarized elliptic parameter group are expanded and perfected, and these parameter groups are redefined, and the mutual transformation relations of these parameter groups are deduced.The correctness of these mutual transformation relations is verified by symbolic mathematical numerical and simulation results. The results show that the complete polarization parameter set of electromagnetic wave which contains the initial phase is complete and has a one-to-one correspondence with each other.The relation of parameter group transformation simplifies the complicated calculation process of electromagnetic wave polarization and provides a more complete and applicable scheme for the theory and application design of electromagnetic wave polarization. It has theoretical reference and application value.
