The finite difference time domain (FDTD) algorithm and Green function algorithm are implemented into the numerical simulation of electromagnetic waves in Schwarzschild space-time. FDTD method in curved space-time is developed by filling the flat space-time with an equivalent medium. Green function in curved space-time is obtained by solving transport equations. Simulation results validate both the FDTD code and Green function code. The methods developed in this paper offer a tool to solve electromagnetic scattering problems. @@@ Program summary @@@ Program Title: FDTD and Green function in Schwarzschild space-time @@@ Program Files doi: http://dx.doLorg/10.17632/8 fxbp578ys. 1 @@@ Licensing provisions: GPLv3 @@@ Programming language: MATLAB @@@ Nature of problem: Simulating electromagnetic waves in Schwarzschild space-time. @@@ Solution method: FDTD method and Green function method.
