M. Atiqur Rahman, M. Hossain Ali

摘要:

利用时空3+1分裂研究了在Reissner-Nordström-de Sitter黑洞引力场影响下的相对论性双流体等离子体中横向电磁波的传播.通过对双流体方程的重新表述,导出了微扰的线性方程组。利用局域近似方法,研究了Alfvén波和高频电磁波的一维径向传播。这些波的色散关系,得到和数值求解的波数。

英文摘要:

The transverse electromagnetic waves propagating in a relativistic two-fluid plasma influenced by the gravitational field of the Reissner-Nordström-de Sitter black hole has been investigated exploiting 3+1 split of spacetime. Reformulating the two-fluid equations, the set of simultaneous linear equations for the perturbations have been derived. Using a local approximation, the one-dimensional radial propagation of Alfvén and high frequency electromagnetic waves are investigated. The dispersion relation for these waves is obtained and solved numerically for the wave number.
