Abstract Perturbed effect of high-frequency gravitational radiation produced by microwave electromagnetic (EM) cavity on static detecting EM field is investigated, and corresponding perturbation solutions have been given. It is found that the gravitational wave (GW) beam propagating along symmetric axis of the cavity is purely +type polarized in transverse traceless coordinate system, and it can make the static EM field generate a cumulative perturbed effect which is proportional to the time. For the gravitational radiation wave beams propagating along other directions, they are usually mixed radiation of + and x type polarization. Quality factor of the cavity plays a key role in interaction strength of the GW with the detecting EM field.
