Plasma wave properties of the Schwarzschild magnetosphere in a Veselago medium

Abstract

We re-formulate the 3 + 1 GRMHD equations for the Schwarzschild black hole in a Veselago medium. Linear perturbation in rotating (non-magnetized and magnetized) plasma is introduced and their Fourier analysis is considered. We discuss wave properties with the help of wave vector, refractive index and change in refractive index in the form of graphs. It is concluded that some waves move away from the event horizon in this unusual medium. We conclude that for the rotating non-magnetized plasma, our results confirm the presence of Veselago medium while the rotating magnetized plasma does not provide any evidence for this medium.

“…The comparison of the results for isothermal [33] and hot plasma can be summarized in the following table. Normal at random points Normal in most of the region in Figures 3 and 4 The difference between our work and previous work is that we have used the variable specific enthalpy and previous work has been done using constant specific enthalpy.…”

“…Veselago [32] verified the concepts related to the energy, linear momentum and mass transferred by an electromagnetic wave in a negative refraction medium. In a recent paper [33], we have discussed the isothermal plasma wave properties for the Schwarzschild magnetosphere in a Veselago medium. The results verified the presence of this medium for only rotating non-magnetized plasma.…”
