Can a system be engineered to cause a standing wave resonance with gravitational waves?

It appears that gravity waves can be reflected. Do Mirrors for Gravitational Waves Exist? Stephen J. Minter, Kirk Wegter-McNelly, Raymond Y. Chiao https://arxiv.org/abs/0903.0661

Could someone engineer a system, using those mirrors?

  • $\begingroup$ @PaulChilds Out of curiosity, what's the difference between"practically" and "logistically" in this context? $\endgroup$ – probably_someone May 24 at 12:18
  • $\begingroup$ Both theoretically, and practically, using ambient gravity waves from black hole collisions. $\endgroup$ – Don Bob May 24 at 12:24
  • $\begingroup$ Do you have some target figure in mind for a cavity quality factor? E.g. that someone could build a GWaser? $\endgroup$ – Paul Childs May 24 at 12:40
  • $\begingroup$ Would the quality factor need to be on the lower end, so it will work with a wider range of frequencies? $\endgroup$ – Don Bob May 24 at 12:48

Can a system be engineered to cause a standing wave resonance with gravitational waves?

This is precisely how the first attempt to measure gravity waves worked. It consisted of a large metal cylinder, cooled to remove thermal noise. If a gravity wave passed it would being to resonate, which would be detected via piezo sensors.

Unfortunately the S/N ratio was far below what we now know to be required.

  • $\begingroup$ It did so through reflection, in essence, but in the same fashion that a guitar string does when the wave hits the frets. This is basically what a standing wave is, the amplification of a single wave by reflecting it back on itself in a particular way. Note that most radio antennas also work in this fashion. $\endgroup$ – Maury Markowitz Jun 6 at 15:36
