US Army scientists have demonstrated a new quantum sensor that can measure the full 3D direction of radio-frequency electromagnetic fields, a milestone that could reshape how signals are detected on ...

Abstract: Optical tactile sensors have recently become popular. They provide high spatial resolution, but struggle to offer fine temporal resolutions. To overcome this shortcoming, we study the idea ...

Abstract: This letter focuses on the passive localization of a moving source in the presence of random sensor location errors. We propose a modified two-stage closed-form method that takes the sensor ...
