The Ionosphere is the conducting region of the upper atmosphere                 produced by absorbtion of solar ultraviolet light. It interacts                 strongly with radio waves and reflects, refracts and absorbs them               depending on the frequency. When irradiated with sufficiently                   powerful radio waves of appropriate frequency it will absorb                    sufficient power to become heated, form localised plasma density                enhancements, emit energetic electrons, and emit light.  The                    approach being explored under this award involves irradiation by                two radio beams with closely spaced frequencies, which are                      expected to produce ionospheric oscillations at the beat                        frequency, and thus act as a radio transmitter for very low                     frequencies without the need for a huge antenna on the surface.                 This work provides insights into the fundamental physics of                     ionized media, and may have practical applications for                          communication.
