40th ESA Antenna Workshop, 8-10 Oktober, 2019, Noordwijk, The Netherlands
Radio-telescopes or ground-station antennas can, if pointed, act as a radar target with high radar cross-section (RCS). Space-based Synthetic Aperture Radar (SAR) data confirmed it at 5:3GHz for a modified ground-station antenna. Operational ground-s

This paper presents the results from one of the first observations of ionospheric scintillation taken using the Low-Frequency Array (LOFAR). The observation was of the strong natural radio source Cas A, taken overnight on 18-19 August 2013, and exhib

The four persistent radio sources in the northern sky with the highest flux density at metre wavelengths are Cassiopeia A, Cygnus A, Taurus A, and Virgo A; collectively they are called the A-team. Their flux densities at ultra-low frequencies (<100 M

Ion specific outcomes at aqueous interfaces remain among the most enigmatic phenomena in interfacial chemistry. Here, charged fused silica/water interfaces have been probed by homodyne- and heterodyne-detected (HD) second harmonic generation (SHG) sp
