Because of the huge computation and limitation of computer resource when modeling the diffuse of the transient field in three dimensional medium, FDTD, the nonuniform grid and time step length will be used to study the whole-space response characteristic of two dimensional square and sheet conductive body, located both in uniform medium, and in the layered medium, with a 3 dimensional magnetic dipole, And the diffused regularity of the transient field in them, the effect of laneway and boundary will be also discussed. The objectives are to provide interpretation guidelines for the TEM anomalies arising from the full-space uniform and layered medium.
