Diffraction of plane radio waves by a parabolic cylinder
Abstract: Expressions are given for the diffraction field far behind, and the surface currents on, a parabolic cylinder. Approximate values for the field strength and current density are given when ...

Radio propagation fundamentals
and diffraction over the earth's surface. In this paper, radio transmission theory and experiment in all frequency bands of current interest are summarized. Ground wave and sky wave transmission are ...
Less than 1% of the world’s biggest radio telescope is complete – but its first image reveals a sky dotted with ancient galaxies
The SKA-Low radio telescope in Western Australia is slowly coming online. It will probe the shape of the universe and study ...
Fast Radio Bursts Explained? Scientists Zero In on Their Mysterious Origins
A research team led by McGill identifies neutron stars as the likely source of fast radio bursts, one of the universe's most ...

Mysterious radio pulses from the Milky Way ‘are unlike anything we knew before’
But de Ruiter didn’t think the star would be able to produce radio waves by itself. Something else had to be instigating it.The pulses differed from fast radio bursts, which are incredibly ...
Astronomers investigate X-shaped radio galaxy 3C 315
By analyzing the data from Leahy's atlas of double radio-sources and NASA/IPAC Extragalactic Database (NED), Serbian ...
Researchers created sound that can bend itself through space, reaching only your ear in a crowd
Controlling where sound goes is difficult because of a phenomenon called diffraction – the tendency of sound waves to spread out as they travel. This effect is particularly strong for low-frequency ...
