The numerical method for derivation of diffraction coefficients of wedge characterized by fractal surfaces is described.We use the Finite-difference Time-domain (FDTD) method to compute the scattered field of an object possessing several scattering centers.The numerical diffraction coefficient of the scattering center under investigation is then obtained by solving simultaneous equations established via GTD consideration. The examples show the feasibility of the present method.
