Anomalous absorption of electromagnetic waves by 2D transition metal carbonitride Ti3CNTx (MXene)
Science, 2020Shields up! Specialized conductive materials are used to shield or block electromagnetic radiation such as microwaves or radio waves to either prevent the escape of stray radiation or prevent interference from unwanted sources.

Analysis of rotational Doppler effect based on radio waves carrying orbital angular momentum
Journal of Applied Physics, 2018The electromagnetic beam carrying orbital angular momentum (OAM) has a twisted phase front, which can induce a rotational Doppler frequency shift when it is illuminating on a spinning object.

A bright millisecond-duration radio burst from a Galactic magnetar
Nature, 2020Magnetars are highly magnetized young neutron stars that occasionally produce enormous bursts and flares of X-rays and γ-rays1. Of the approximately thirty magnetars currently known in our Galaxy and the Magellanic Clouds, five have exhibited transient ...

A fast radio burst localized to a massive galaxy
Nature, 2019Intense, millisecond-duration bursts of radio waves (named fast radio bursts) have been detected from beyond the Milky Way1. Their dispersion measures—which are greater than would be expected if they had propagated only through the interstellar medium of

Transactions of the American Institute of Electrical Engineers, 1926
UNTIL rather recently, the practise of radio communication was confined to the use of long, earth-bound waves. These waves are preferred on account of the regularity of day and night operation and the absence of fading. The characteristics of the earth-bound wave were extensively explored and there was a tendency to generalize these results assuming ...

Radio Wave Tomography: Imaging Ore Bodies Using Radio Waves
3rd SAGA Biennial Conference and Exhibition, 1993Radio tomography (RT) extrapolates geological information between boreholes, by producing attenuation images of the intervening rockmass. In this paper the underlying principles of this novel geophysical technique are described, and case studies from a variety of geological and rnining environments are presented.

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.
