引力波尾流中的电磁波和Stokes参数
Electromagnetic waves and Stokes parameters in the wake of a gravitational wave
摘要:
本文给出了(弱)引力波背景下的电磁波的理论描述。本文给出了Ehlers-Kundt度规描述的平面前引力波通过时Stokes参数的显式表达式。特别是,它示出的偏振椭圆的轴振荡,其椭圆率保持不变。
英文摘要:
A theoretical description of electromagnetic waves in the background of a (weak) gravitational wave is presented. Explicit expressions are obtained for the Stokes parameters during the passage of a plane-fronted gravitational wave described by the Ehlers-Kundt metric. In particular, it is shown that the axis of the polarization ellipse oscillates, its ellipticity remaining constant.
