Abstract
We investigate wave attributes of hot plasma around a Reissner–Nördstrom–de Sitter (RN-dS) metric in a Veselago
medium. A perturbation scheme is implemented on general relativistic magnetohydrodynamical (GRMHD) equations that are
further used for Fourier analysis. The linearly perturbed Fourier-analyzed GRMHD equations depict the dispersion of hot plasma
waves. It is found that inclusion of charge in de Sitter space greatly affects the wave dispersion. A comparison of wave properties
is presented, and results reassert the presence of the Veselago medium.
