论文摘要
结果表明，在分散培养基中与背景下灯膜下引力波相相传播的亚延伸电磁等离子体波可以经历参数扩增。为了使这种现象发生，必须正确匹配两个波的分散特性。两个波的响应频率（中依赖）必须在确定的限制范围内。组合的动力学由惠特克 - 希尔方程表示，这是参数不稳定性的典型模型。电磁波的指数生长在共振下显示；血浆波以背景重力波为代价生长。讨论了现象的不同物理场景。
It is shown that a sub-luminal electromagnetic plasma wave, propagating in phase with a background sub-luminal gravitational wave in a dispersive medium, can undergo parametric amplification. For this phenomena to occur, the dispersive characteristics of the two waves must properly match. The response frequencies of the two waves (medium dependent) must lie within a definite and restrictive range. The combined dynamics is represented by a Whitaker-Hill equation, the quintessential model for parametric instabilities. The exponential growth of the electromagnetic wave is displayed at the resonance; the plasma wave grows at the expense of the background gravitational wave. Different physical scenarios, where the phenomenon can be possible, are discussed.
