Generation and Registration of High--Frequency Coupled Gravitational Waves

The paper describes the process of generating a coupled gravitational wave as a result of two electromagnetic waves propagating in a vacuum, the frequency of one wave being two times that of the other. We show that when a coupled gravitational wave interacts with two strong electromagnetic waves, lower frequency harmonics are generated. We consider the case of generating a coupled standing gravitational wave by means of strong standing electromagnetic waves and recording said gravitational wave as it interacts with these electromagnetic waves. We determined that the sensitivity of modern SQUID magnetometers is adequate for successfully conducting a laboratory experiment in generating and recording coupled high-frequency gravitational waves.
