  Reflection and Transmission Coefficients of Electromagnetic Wave Equation in Schwarzschild Black Hole
  Author(s): Gopal Neupane*
  
  The electromagnetic perturbation to the Schwarzschild metric is studied. The perturbation of the Schwarzschild black hole is described by the general time-dependent Regge-Wheeler equation. We trasnform this equation to usual Schwarzschild coordinates. In this case, it is possible to separate a harmonic time-dependence. Then, the resulting radial equation belong to the class of confluent Heun equation consisting of effective potential. The potential behaves like 1-D potential barrier in elementary quantum mechanics which is used to calculate the reflection and transmission coefficients near the Schwarzschild space-time using black hole boundary condition and the properties of confluent Heun function...
