The Physics of Fast Radio Bursts
Fast radio bursts (FRBs), millisecond-duration bursts prevailing in the radio sky, are the latest big puzzle in the universe and have been a subject of intense observational and theoretical investigations in recent years. The rapid accumulation of the observational data has painted the following sketch about the physical origin of FRBs: They ...

The Physics of Fast Radio Bursts [PDF]
In 2007, a very bright radio pulse was identified in the archival data of the Parkes Telescope in Australia, marking the beginning of a new research branch in astrophysics. In 2013, this kind of millisecond bursts with extremely high brightness temperature takes a unified name, fast radio burst (FRB).

MeerKAT Uncovers the Physics of an Odd Radio Circle
ABSTRACT Odd radio circles (ORCs) are recently-discovered faint diffuse circles of radio emission, of unknown cause, surrounding galaxies at moderate redshift (z ∼ 0.2 – 0.6). Here, we present detailed new MeerKAT radio images at 1284 MHz of the first ORC, originally discovered with the Australian Square Kilometre Array Pathfinder, with ...

Learning Radio Maps for Physical-Layer Security in the Radio Access
2019 IEEE 20th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2019While there is an evident trend towards “strengthening” the notion of secrecy in information-theoretic analyses, there remains the question of the assumptions under which the promises of physical-layer security may be delivered. A critical aspect here is the level of knowledge of the inherently uncertain wireless environment, required in order to be ...

Chaos, Periodicity, and Quasiperiodicity in a Radio-Physical Oscillator
International Journal of Bifurcation and Chaos, 2017We report parameter planes displaying dynamical behaviors of a radio-physical oscillator system, which is modeled by a set of four-parameter three autonomous first-order nonlinear ordinary differential equations. Each parameter plane is numerically computed, and the dynamical behavior of each point is characterized by using the respective Lyapunov ...

Communications Techniques in Radio Physics and Astronomy
IEEE Communications Magazine, 1986Techniques used at the Arecibo Observatory's giant radio telescope in the areas of planetary radar astronomy, passive radio astronomy, and radar studies of the ionosphere and neutral atmosphere are described. Pulse compression, range-Doppler processing, and digital decoding in planetary studies are examined.

On physical layer security for cognitive radio networks
IEEE Network, 2013In this article we explore the security issues on physical layer for cognitive radio networks. First we give an overview on several existing security attacks to the physical layer in cognitive radio networks. We then discuss the related countermeasures on how to defend against these attacks.
