An exotic variant of this radio wave propagation has been examined to show that, theoretically, the ionospheric bounce could be greatly exaggerated if a high powered spherical acoustical wave were created in the ionosphere from a source on earth.

They also have applications in heart beat monitors, weapon systems positioning, sensors in anti-locking brakes, weather prediction ( via solar cycles ), steel pylons, drill guidance systems, archaeology, plate tectonics and radio wave propagation and planetary exploration.

Hagfors's research was very broad, comprising amongst other things ionospheric modification ( heating ), radar astronomy within our solar system, observations of planetary surfaces from space, techniques in radio remote sensing, scattering from rough surfaces, antennas and radio wave propagation.

He elaborated on World Wireless in his 1919 " Electrical Experimenter " article titled " " The True Wireless, " " detailing its ability for long range telecommunications and putting forward his view that the prevailing theory of radio wave propagation was inaccurate.

As was proposed by secretary academician L . A . Artsimovich, construction of the Institute building was planned to take place in the Krasnaya Pakhra Scientific Centre, which was being developed at the time and already included the Pushkov Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation and Institute for High Pressure Physics.

He also described the problem that confronts the scientific community, that each scientist must evaluate the record for himself, and that the " Report "'s recommendation against further research " may not be true for all time . " He advised that government agencies and private foundations " ought to be willing to consider UFO research proposals . . . on an open-minded, unprejudiced basis . . . . [ E ] ach individual case ought to be carefully considered on its own merits . " In particular, the " Report " noted that there were gaps in scientific knowledge in the fields of " atmospheric optics, including radio wave propagation, and of atmospheric electricity " that might benefit from further research in the UFO field.
