Abstract We present a new detecting scheme of high-frequency gravitational waves (HFGWs) in the GHz band, the scheme consists of a high-quality-factor open microwave cavity, a static magnetic field passing through the cavity and an
electromagnetic (EM) normal mode stored in the cavity. It is found that under the resonant condition first- and second-order perturbation EM effects have almost the same detecting sensitivity to the HFGWs in the GHz band (h～10-26,ν～5GHz), but the former contains more information from the HFGWs. We also provide a very brief review for possible improving way of the sensitivity.
This scheme would be highly complementary to other schemes of detecting the HFGWs.
