Utilization of electromagnetic detector for selection and detection of high-frequency relic gravitational waves

TL;DR

This paper proposes a method using fractal membranes and Gaussian beams in a static magnetic field to selectively detect high-frequency relic gravitational waves by analyzing electromagnetic perturbations.

Contribution

It introduces a novel electromagnetic detection scheme that enhances the selectivity for relic gravitational waves based on their propagation direction.

Findings

The coupling system effectively distinguishes GW components propagating along the positive axis.

Relic GWs propagating along other directions produce significantly weaker electromagnetic signals.

Random fluctuations of relic GWs do not significantly affect the detection capability.

Abstract

It is shown that coupling system between fractal membranes and a Gaussian beam passing through a static magnetic field has strong selection capability for the stochastic relic gravitational wave background. The relic GW components propagating along the positive direction of the symmetrical axis of the Gaussian beam might generate an optimal electromagnetic perturbation while the perturbation produced by the relic GW components propagating along the negative and perpendicular directions to the symmetrical axis will be much less than the former.The influence of the random fluctuation of the relic GWs to such effect can be neglected and the influence of the random fluctuation of the relic GWs to such effect can be neglected.
