A review of the recent work on scattering draws attention to a number of discrepancies in the interpretation of the data. Most workers believe that the scattering is due to clouds in the E layer. The experiments described in this paper indicate that there are several types of scattering phenomena.

Proceedings of the IRE, 1934
Following the magneto-ionic theory of Appleton-Hartree, an explanation for the existence of echoes of long delay has been formulated. Realizing that the ordinary and extraordinary rays have opposite senses of polarization, it may be seen that one of these rays will penetrate the E layer while the other may not.

Radio waves in the heliosphere
Advances in Space Research, 1993Abstract Solar radio emissions at long wavelengths (wavelengths greater than 10 m or frequencies smaller than 30 MHz) are produced in the upper corona and in the interplanetary medium (the Heliosphere), sometimes at very large distances from the Sun, up to the orbit of Jupiter and beyond. Solar radio emissions are produced by the passage of energetic

Electromagnetic radio waves traveling within earth’s atmosphere are called terrestrial waves, and communications between two or more points on earth is called terrestrial radio communications. Terrestrial waves are influenced by the atmosphere and earth itself.

IRE Transactions on Antennas and Propagation, 1957
The formulas required for simple accurate numerical evaluation of the radiation patterns from slots on large circular cylinders are derived. From the usual harmonic series, integral representations are obtained. These lead to either the residue series via the Watson transformations or to the geometrical-optics representations via a saddle-point ...

Mike O'Sullivan visits Radio Nikosia, a radio station in Barcelona run by people with mental health problems that broadcasts to the city once a week. He believes the time is ripe for just such a radio station here in the UK, to empower service users and challenge stigma.

Three planets, the earth, Jupiter and Saturn are known to emit nonthermal radio waves which require coherent radiation processes. The characteristic features (frequency spectrum, polarization, occurrence probability, radiation pattern) are discussed. Radiation which is externally controlled by the solar wind is distinguished from internally controlled ...
