Two-dimensional materials expand options for next-generation terahertz quantum devices

Scientists from the National University of Singapore (NUS) have discovered that atomic-scale substitutional dopants in ultra-thin two-dimensional (2D) materials can act as stable quantum systems ...

Velocity gradients prove key to explaining large-scale magnetic field structure

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

Dynamic Metasurface Antenna Based Anti-Jamming With Bit-Limited ADC

Abstract: In adversary suppressive jamming scenarios, digital receivers necessitate high-resolution analog-to-digital converters (ADCs) to prevent nonlinear distortion of signal waveforms due to ADC ...
