Two-dimensional materials are substances with a thickness of a few nanometres or less. Electrons in these materials are free to move in the two-dimensional plane, but their restricted motion in the ...

If you twist something — say, spin a top or rotate a robot’s arm — and want it to return to its exact starting point, ...

Abstract: This paper presents a grid-based design framework for rotated subarray configurations to address the grating lobe (GL) suppression challenge in large-spacing arrays (element spacing > ...

Abstract: Phased array calibration is crucial for ensuring the performance of phased arrays. Calibration methods based on amplitude - only measurements, such as the rotating - element harmonic ...
