Abstract: A frequency reconfigurable tightly coupled dipole array (TCDA) based on PIN diodes is demonstrated in this paper. Two different operating bands of the proposed array can be selected by ...

Abstract: Frequency Diverse Array is an advanced antenna technology for clustering received power spatial distribution in specific areas, which has shown significant potential in many applications, ...

A team of astronomers have made a fascinating discovery that forces us to rethink our understanding of how dead stars behave. Using the powerful Low Frequency Array (LOFAR) radio telescope in the ...

Radio astronomy has long been unsung and underappreciated, largely because it's never been able to cough up the kind of jaw-dropping visual images that are routine with large optical telescopes. But ...

Radio observations of Stephan’s Quintet at different frequencies, taken by the Low Frequency Array (LOFAR) and the Very Large Array (VLA). The red colors indicate strong radio emission coming from the ...

This code repository contains a Python wrapper for the NTIA/ITS implementation of the Low Frequency / Medium Frequency (LF/MF) Propagation Model. LF/MF predicts basic transmission loss in the ...

Observations by the Low Frequency Array (LOFAR) radio telescope reveal that Starlink’s second-generation (V2-mini) satellites emit significantly elevated levels of unintended electromagnetic radiation ...

In a time of worldwide stress and upheaval, many individuals are searching for an uncomplicated and effortless method of reducing their feelings of stress and tension. Recently, several studies have ...
