DESCRIPTION:Speakers: Luca Marsili ()\nWith the first detection of gravita
 tional waves in 2016 a new window on the observation of the Universe has b
 een opened. This has made possible several new tests of general relativity
 \, discoveries on the physics of black holes\, and opened a new way of stu
 dying physics beyond the Standard Model. There is evidence that the Standa
 rd Model (SM) of particle physics is not the ultimate description of natur
 e as it cannot explain neutrino masses\, dark matter\, and the baryon asym
 metry of the Universe\, gravitational waves could be one of the main tools
  to answer to this question. \nSo far\, gravitational waves have been det
 ected only at low frequencies: at nHz for the recent stochastic background
 \, and 10-100 Hz from the observations of LIGO-VIRGO and KAGRA. Several wo
 rks showed how it would be possible to get important new information relev
 ant to theoretical particle physics and cosmology at higher frequencies\, 
 from MHz to GHz.\nIn this project we revisit the work "2000 Class. Quantum
  Grav. 17 2525” by A. M. Cruise\, and discuss the validity of the geomet
 rical optics approximation in electromagnetic detectors for very high-freq
 uency gravitational waves\n\nhttps://indico.ific.uv.es/event/7664/contribu
