Abstract: This communication introduces an innovative approach to achieving an ultrawideband (UWB) reconfigurable multinotch band antenna. The antenna's performance is dynamically tuned using a ...
Abstract: We propose a simultaneous multifrequency near-field radio holography method for measuring reflector surfaces of radio telescopes with high precision. With a comb spectrum generator as the ...
A team of physicists at the University of Warsaw has built the world’s first all-optical radio receiver powered entirely by laser light. The device, developed by researchers from the Faculty of ...
October 14 (SeeNews) - The European High Performance Computing Joint Undertaking (EuroHPC JU) said it has selected entities from 13 countries, including Moldova, North Macedonia, and Serbia, to act as ...
A “thoughtful” 71-year-old disabled radio amateur has applied for permission to install a reinforced concrete base station for his 9m back garden antenna. Peter Crowley moved to Telford last year ...
The largest of three newly found ring shaped structures in the cosmos are almost a million light-years across. Citizen scientists have found several new "odd radio circles<" or ORCs, in distant, ...
Amateur radio operators have always been early adopters of new technology, but the transition to electric vehicles presents challenges that go far beyond learning new equipment. The electromagnetic ...
ESA has inaugurated a powerful new 35-meter deep space antenna at its New Norcia site in Western Australia, marking a major boost to Europe’s ability to communicate with spacecraft exploring the Solar ...
