Abstract: In this paper we examine the wave properties of hot plasma living inSchwarzschild magnetosphere. The 3+1 GRMHD perturbation equations areformulated for this scenario. These equations are Fourier analyzed and thensolved numerically to obtain the dispersion relations for non-rotating,rotating non-magnetized and rotating magnetized plasma. The wave vector isevaluated which is used to calculate refractive index. These quantities areshown in graphs which are helpful to discuss the dispersive properties of themedium near the event horizon.
