“…The intensities of the PPFs generated by the former will be one to two orders of magnitude smaller than those generated by the latter. But it is not impossible to probe the stochastic and incoherent HFGWs [35][36][37]. Now, we have calculated the PPFs of various situations, including the PPFs generated by the pure ⊗-type polarization the HFGWs [see Eqs.…”

We consider the perturbative photon flows (PPFs, i.e., electromagnetic (EM) counterparts) generated by the EM resonance response to high-frequency gravitational waves (HFGWs) with additional polarization states in a rotating laboratory frame system. It is found that when the propagating direction of the HFGWs and the symmetrical axis of the laboratory frame system are the same, the PPFs have the maximum value. In this case, using the rotation (the rotation of azimuth φ) of the EM detection system, all six possible polarization states of the HFGWs can be separated and displayed. For the current experimental conditions, it is quite prospective to detect the PPFs generated by the HFGWs predicted in the braneworld models, the primordial black hole theories and the interaction mechanism between astrophysical plasma and intense EM radiation, etc., due to the large amplitudes (or high spectral densities) and spectral characteristics of these HFGWs. Detecting the primordial HFGWs from inflation faces great challenges at present, but it is not impossible.

Based on the modulated Gaussian beam, the feasibility of the Li-Baker detector to detect gravitational wave in GHz band is investigated in this paper. The first-order perturbation photon fluxes (PPF, signal of the detector) and the background photon fluxes (BPF, main noise of the detector) varing with time and transverse distance are calculated, which show their propagation directions and energy densities are much different in some areas. Apart from BPF, we also consider other two important noises: diffraction noise and shot noise. In the simulation, it is found that the diffraction noise and shot noise are both lower than the signal. Meanwhile, the main noise (BPF) can be eliminated when the receiving screen location is chosen to be in some special transverse areas where BPF direction is opposite to PPF. So that the signal to noise ratio (SNR) of our detection can reach up to $320$ at some transverse areas. These results are benefit for the design of the Li-Baker detector.
