Abstract: The scattering of waves from a cylindrical obstacle burried in the dielectric half-space can be investigated by many means. One of them is discrete method. But it is difficult to deal with the radiation conditions on the artificial boundaries of finite calculating region. To eliminate the effects of waves reflected from the artificial boudaries, an Artificial Transmitting Boundary Method was given by seismology circles and has been applied to some scattering problems successfully/In this paper, as a trial, the method mentioned above is combined with Finite Element Method and applied to give out the near-field solutions. Then, making use of the results, the far-field solutions are given with Green's function method. Finally, the results from the method used here are compared with those from the integral equations method. It is verified that the new method used here is feasible.
