摘要

为了考虑电磁波的动力学,可以提出不同于所观察到的值的各种表示。以下可以作为这样的值:电强度和磁感应矢量,电强度和磁感应矢量或矢量电位。最后,场振幅或能量特征,包括偏振状态的描述,可以作为观测值。选择待观察的特征后,可以描述偏振态。关键是,任何由同构(相互无二义性)转换连接的描述都是彼此完全等价的:从一个描述传递到另一个描述而不丢失任何内容是可能的

Quaternion presentations polarization state
For considering the dynamics of an electromagnetic wave, a variety of presentations differing in the values being observed can be suggested. The following can be used as such values: electric intensity and magnetic induction vectors, electric and magnetic intensity vectors or vector potential. Finally, field amplitude or energetic characteristics, including, the description of the polarization state, can be used as observed values. The polarization state can be described after characteristics to be observed have been chosen. The point is that any descriptions connected by isomorphic (mutually unambiguous) transformations are completely equivalent to each other: it is possible to pass from one description to the other without losing anything from its contents.<>
