A bright millisecond-duration radio burst from a Galactic magnetar

Nature, 2020
Magnetars 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 ...

Monitoring gait at home with radio waves in Parkinson’s disease: A marker of severity, progression, and medication response

Science Translational Medicine, 2022
Parkinson’s disease (PD) is the fastest-growing neurological disease in the world. A key challenge in PD is tracking disease severity, progression, and medication response. Existing methods are semisubjective and require visiting the clinic. In this work,

Anomalous absorption of electromagnetic waves by 2D transition metal carbonitride Ti3CNTx (MXene)

Science, 2020
Shields 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, 2018
The 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 fast radio burst localized to a massive galaxy

Nature, 2019
Intense, 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

Polarization of Radio Waves

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, 1993
Radio 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.
