摘要
We study in detail both the lateral wave and trapped surface wave generated by a vertical electric dipole over the air-dielectric boundary on a wide range medium such as sea and lake water and wet and dry earth. Graphs of the far-field pattern are shown and compared with the available results. Especially, when both the dipole point and the observation point are on the surface of dielectric-coated earth, the trapped surface wave is dominant.
