Considering the antenna mutual coupling problems on electrically large platforms, a fast algorithm of Time Domain Integral Equation (TDIE) based on the Geometry Theory of Diffraction (GTD) is proposed. On the basis of classical Marching-On in Time (MOT) solver, diffraction ray tracing method in GTD is introduced, and the calculation efficiency of retarded-time integral is raised. Numerical results prove that the proposed method can accelerate the process of MOT, and has the theoretical advising meaning towards the optimization design of antennas layout on electrically large platforms.
