| Abstract: | By heating the ionosphere with large ELF/VLF-modulated HF wave, a virtual antenna is produced in the ionosphere, which is an effective means to radiate ELF/VLF waves. This paper uses the modulated-heating models of Wang Feng (2009) to calculate the strength of the LF radiation source produced by HF heating, uses full-wave model to analyze attenuation and reflection of the LF wave transmitting downward, and with HAARP experiment parameter, simulates magnetic field of the LF signals on the sea, which is in PT order, according with the experimental data. |
