| Abstract: | The far zone numerical diffraction coefficient is computed by using the finite difference time domain (FDTD) method and time gating technigue. The contribution of a scattering center of interest, such as a wedge or groove, is isolated effectively from the transient response of an object. Some results of the far zone numerical diffraction coefficients for an electrically small groove are presented by additionally using perturbation method. |
