Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, ...
Abstract: In this letter, we propose a hybrid bonding process for the preparation of micro-light-emitting diode (Micro-LED) based on asymmetric structures. This process employs a bonding system ...
Abstract: Virtual impedance (VI) is widely used in grid-forming (GFM) converters to improve adaptability to stiff grid. However, there are various forms and positions of VI, and the impact of ...
