| Abstract: | In this paper, the radiation of the horizontal electric dipole and the characteristics of electromagnetic wave propagating in the loss medium are discussed. When the electromagnetic pulse propagates in the dispersive medium, some distortions of waveform will occur as shown in the calculated examples. |
