The EM Fields Produced by a Moving Horizontally-Directed Time-Harmonic Dipole in Two-layer Media

In order to really apply the shaft-rate electromagnetic(EM)fields to new type mine fuze,the EM fields at a fixed field point produced by a moving horizontally-directed time-harmonic dipole,located in the two-layer media were derived.The whole process was divided into two steps,in the first place,the EM fields at a fixed field point produced by a static dipole were derived;then based on the basic principle of the special theory of relativity and Lorentz transformation,the EM field produced by the moving dipole were derived;in the end,taking a ELF dipole moving slowly in the deep ocean for example,the numerical calculations of its EM fields were carried out.The practicality and correctness of the results were proved through contrasting the results with the experimented data.
