Concrete forms of resonant response (ER) for a strong electromagnetic (EM)
wave beam (photon flux) propagating in a static magnetic field to a standin
g gravitational wave (gravitons) are given, and the corresponding perturbat
ion solutions and resonant conditions are obtained. It is found that pertur
bed EM fields (PEMFs) contain three new components with frequencies \omega
(g) +/- omega (e)\ and omega (g), respectively. In the case of omega (e)muc
h greater than omega (g), the PEMFs are manifested as the EM wave beams wit
h frequency omega (e) and a standing EM wave with omega (g). The former and
the background EM wave beam (BEMWB) have the same propagating direction, w
hile in the case of omega (g)much greater than omega (e), all PEMFs are exp
ressed as the standing EM waves with frequency omega (g). The resonant resp
onse occurs in two cases of omega (e) = 1/2 omega (g) and omega (e) = omega
(g) only. Then not only the first order perturbed energy fluxes (PEFs) pro
pagating in the same and opposite directions of the BEMWB can be generated,
but also radial and tangential PEFs which are perpendicular to the above d
irections can be produced. This effect might provide a new way for the EM d
etection of the gravitational waves (GWs). Moreover, the possible schemes o
f displaying perturbed effects induced by the standing GW with h = 10(-33)
- 10(-35) and lambda (g) = 0.1 m at the level of the single photon avalanch
e and in a typicla laboratory dimension are reviewed.
