摘要

This paper analyses the field generated by the artificial ionospheric modulation of ELF/VLF wave on the sea surface. Ionospheric artificial modulation of ELF/VLF waves is helpful to understand the physical processes in the ionosphere, and analyze the new phenomenon. By artificially modulating the ionosphere to excite the ELF/VLF wave, the disadvantages of the traditional antenna system are overcome, such as large occupied area and difficult erection. In view of the VLF transmitter on the low earth orbit satellite, the distance between the transmitter and the underwater receiving submarine can be greatly shortened by the operation of the satellite. As a new research on submarine communication system, the transmitting and transmission of VLF waves are worth exploring. When the VLF wave transmitter carried by the satellite uses a slender antenna for the communication to submarines the slender antenna locates in the F-layer of 400km. As the simplest model, the slender antenna is idealized as an electric dipole, and the ionosphere is idealized as a homogeneous anisotropic plasma with sharp boundary. The VLF electric field on the sea surface is analyzed and calculated.
