The Resonance Of A Gaussian Beam In A Static Magnetic Field To High-Frequency Relic Gravitational Waves

The research of High-Frequency Gravitational Waves(HFGW, of frequency higher than ) complements the traditional gravitational waves research(of frequency lower than ), and will open a new window through which the new information of Cosmology, Astrophysics etc can be watched. Therefore it has become a hot point of current General Relativity. The noticeable characteristic of the resonance of a Gaussian beam in a static magnetic field to HFGW is that the resonant dimension may reduce as the order of typical lab size, which will lead to the gap between the theory and the relevant experiment. We discussed the resonance of the Gaussian beam to HFGW, and showed its several features, especially the exact selection to High-Frequency Relic Gravitational Waves expected by inflationary cosmic models.We calculated respectively the interaction between the Gaussian beam and incident HFGW from several special directions, and found the electromagnetic system shows wonderful space accumulation of the perturbative effect, only when the incident HFGW has the same frequency as the Gaussian beam, and it propagates along the same direction as the Gaussian beam. On the other hand, the space accumulation will decreases, or even disappears, when the incident HFGW's propagating direction or frequency vary. So Gaussian beam system performs an exact selection ability.As a dissertation, this paper covers many other aspects. Newtonian gravity and General relativity of Einstein are reviewed, and several progresses of mordern theories of gravitation are introduced. We described some interesting schemes of application, generation, and detection of HFGW. SGBR is the focus of this paper, and we made detailed calculations and discussions. A plane to receive the perturbative photon flux is designed, which helpful to the future experiment to detect HFGW. Finally, we make an imagination of HFGW research.
