Numerical simulation of electromagnetic waves in Schwarzschild spaceātime by finite difference time domain method and Green function method
The finite difference time domain (FDTD) algorithm and Green function algorithm are implemented into the numerical simulation of electromagnetic waves in Schwarzschild spaceātime. FDTD method in curved spaceātime is developed by filling the flat spaceātime with an equivalent medium. Green function in curved spaceātime 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
