对于高频残留引力波,我们考察了高频引力波产生的电磁共振效应,这种效应可以用横向微扰光子通量来描述。在张量-标量比为0.2,谱指数为0,运行指数αt= 0.01的条件下,讨论了横向微扰光子通量的几个性质和数量变化,通过将背景电磁场的纵向磁场分量设为标准高斯形式,并对横向进行波阻抗分析,可以显著改善横向微扰光子通量的性质和数量变化。通过理论计算,当电磁场束腰W 0 = 0.05m,引力波初始随机相位δ=(0.21 +n)π(n= 0,1,2.)时,横向微扰光子通量可达103 s − 1。此外,通过建立合适的波阻抗函数,可以完全消除背景横向光子通量的干扰。
For the relic gravitational waves in high frequency band, we survey the electromagnetic resonance effect generated from the high frequency gravitational waves, which can be described in the transverse perturbative photon fluxes. Under the fixed tensor-scalar ratior= 0.2, spectral indexnt= 0 and running indexαt= 0.01, we discuss several properties and quantity changes of the transverse perturbative photon fluxes, which can be improved significantly through setting the longitudinal magnetic component of background EM field in the standard gaussian form, and wave impedance analysis on the transverse direction. Through the theoretical calculation, the transverse perturbative photon fluxes can reach up to 103s−1with some optimal parameters such as waist of EM fieldW0= 0.05m, initial stochastic phase of gravitational wavesδ= (0.21 +n)π(n= 0,1,2...). Furthermore the interference of the background transverse photon fluxes can be removed completely through establishing a suitable wave impedance function.
