Utilization of electromagnetic detector for selection and detection of high-frequency relic gravitational waves
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 (GW) 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 perturb...
متن کاملObserving Gravitational Waves with a Single Detector
A major challenge of any search for gravitational waves is to distinguish true astrophysical signals from those of terrestrial origin. Gravitational-wave experiments therefore make use of multiple detectors, considering only those signals which appear in coincidence in two or more instruments. It is unclear, however, how to interpret loud gravitational-wave candidates observed when only one det...
متن کاملWideband dual sphere detector of gravitational waves.
We present the concept of a sensitive and broadband resonant mass gravitational wave detector. A massive sphere is suspended inside a second hollow one. Short, high-finesse Fabry-Perot optical cavities read out the differential displacements of the two spheres as their quadrupole modes are excited. At cryogenic temperatures, one approaches the standard quantum limit for broadband operation with...

متن کاملResonant interaction between gravitational waves, electromagnetic waves and plasma flows
In magnetized plasmas gravitational and electromagnetic waves may interact coherently and exchange energy between themselves and with plasma flows. We derive the wave interaction equations for these processes in the case of waves propagating perpendicular respectively parallel with the plasma background magnetic field. In the latter case, the electromagnetic waves are taken to be circularly pol...
