  • NRL Scientists Produce Densest Artificial Ionospheric Plasma Clouds Using HAARP (新闻稿). U.S. Naval Research Lab. 2013-02-25 [5 April 2013]. (原始内容存档于2013-03-02). Using the 3.6-megawatt high-frequency (HF) HAARP transmitter, the plasma clouds, or balls of plasma, are being studied for use as artificial mirrors at altitudes 50 kilometers below the natural ionosphere and are to be used for reflection of HF radar and communications signals. Past attempts to produce electron density enhancements have yielded densities of 4×10⁵ electrons per cubic centimeter (cm³) using HF radio transmissions near the second, third, and fourth harmonics of the electron cyclotron frequency. This frequency near 1.44 MHz is the rate that electrons gyrate around the Earth's magnetic field. The NRL group succeeded in producing artificial plasma clouds with densities exceeding 9×10⁵ electrons cm³ using HAARP transmission at the sixth harmonic of the electron cyclotron frequency.
