Generating Electromagnetic Waves from Gravity Waves in Cosmology

چکیده
Examples of test electromagnetic waves on a Friedmann–Lemâıtre– Robertson–Walker (FLRW) background are constructed from explicit perturbations of the FLRW space–times describing gravitational waves propagating in the isotropic universes. A possible physical mechanism for the production of the test electromagnetic waves is shown to be the coupling of the gravitational waves with a test magnetic field, confirming the observation of Marklund, Dunsby and Brodin [Phys. Rev. D62, 101501(R) (2000)]. E-mail : [email protected] E-mail : shanefarrell [email protected]

The preventive role of Snell’s law in mode conversion from Z- to whistler-mode waves in an inhomogeneous magnetoplasma with a low density
Electromagnetic waves with different modes, such as Z-, whistler-, LO- and RX- modes are found in different regions of the Earth magnetosphere and the magnetosphere of other planets. Since whistler-mode waves influence the behavior of the magnetosphere, and they are used as experimental tools to investigate the upper atmosphere, they are important. On the other hand, the mode conversion process...
