According to the relationship between frequency of gravitational waves and its dimensionless amplitude, we focus on the HFRGWs with ν g =2.9GHz, h ~ 10−30 in the pre-big bang and quintessential inflationary models. The results show the peak value of the transverse BPF (~ 1020s−1) is around |x|=0.08m, where |x| is the transverse distance to the longitudinal symmetrical surface of the GB, while the maximum transverse PPF always appears at x = 0 ( $${N^{(1)}_{x} \sim 2.60\times10^{2}\,{\rm s}^{-1}}$$ with the optimal phase difference between the GB and the resonant component of the HFRGWs δ=(n+0.9)π, n=0, 1, 2 . . .). However, the observable PPF should be ~ 1.19×102s−1 because of the stochastic nature of the HFRGWs' phase. Since the decay speed of BPF is much quicker than PPF, it is hopeful to figure out the signal in some optimal regions. Moreover, we compare the decay speed of BPF and PPF in nature mode, and find the threshold value of x where PPF exceeds to BPF. It demonstrates that the limitation of our detection sensitivity comes from the strength of PPF rather than swamping by BPF. On the other hand, with the fractal membrane, the comparison between BPF and PPF provides the optimal detection area $${x\in[0.28,1]}$$ m. In addition, through the calculation of shot noise and conservative estimation, we find that our sensitivity is h=10−26 in 4months signal accumulate time.
