Coupling Light Waves to Gravitational Waves
Martin W. McCall, Stefanos Fr. Koufidis
We demonstrate analytically that gravitational waves, upon interacting with co-propagating electromagnetic radiation in a plasma, induce distinctive sidebands on the modulated ligh…

Light propagation in time-periodic bi-isotropic media
Stefanos Fr. Koufidis, Theodoros T. Koutserimpas, Francesco Monticone +1
Photonic structures and time-crystals, wherein time is incorporated as an additional degree of freedom for light manipulation, have necessitated the development of analytical and s…
