A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the University of Warsaw has developed a new type of all-optical radio receiver based on the fundamental ...

Abstract: Certain magnetometers produce at their output signals that exhibit double-sideband amplitude modulation with carrier signal (AM) with an ultra-low modulation index (m ≪0.01). This low m ...

Abstract: We present the first demonstration of an acoustic quadrature amplitude modulation (QAM) circuit based on polarization switching of ferroelectric thin films. Electric field control of ...

The evidence is solid but not definitive, as the conclusions rely on the absence of changes in spatial breadth and would benefit from clearer statistical justification and a more cautious ...
