An Interaction With Propagation Of Gravitational And Electromagnetic Waves In Plasma

We Know that the gravitational waves and electromagnetic waves are important as carriers of energy andinformation. This paper is deals with the study of the propagation and interaction of Gravitational wavesin plasmas, with emphasis on nonlinear effects and applications within astrophysics. The physical systemsare described by the Einstein-Maxwell-fluid equations or Einstein-Maxwell-Vlasov equations, when akinetic treatment is required. The small amplitude and high-frequency approximation is employed for thegravitational waves, such that Perturbative techniques can be applied and space-time can be consideredlocally flat, with a gravitational radiation field superimposed on it. The gravitational waves give rise tocoupling terms that have the structure of effective currents in the Maxwell equations and an effectivegravitational force in the equation of motion for the plasma. The Einstein field equations describe theevolution of the gravitational waves, with the perturbed energy-momentum density of the plasma and theelectromagnetic field as a source. The processes that are investigated are gravitational waves excitingelectromagnetic waves in plasmas, altering the optical properties of plasmas and accelerating chargedparticles.
