Metasurface Holography on a Relative-Phase Manifold for Stable and High Fidelity Tweezer-Array Generation

Yichen Zhu, Zifeng Li, Xiaopeng Li, Jiacheng Sun et autres

We present a new holographic approach for generating large scale, polarization resolved optical tweezer arrays. By analyzing the ideal Jones fields that realize a target pattern, we identify that the fundamental degrees of freedom are the relative phases of the individual tweezers, …

An adaptive synchronous loop phase compensation method for enhancing grid-forming transient stability

Yang Cui, Boyu Ma, Zifeng Li, Yuting Zhao

While virtual inductance in grid-forming control effectively reduces inrush current, it negatively impacts transient stability. This study proposes a synchronous loop control strategy incorporating an adaptive adjustment mechanism to improve power angle stability and dynamic response performance in grid systems. Initially, the …
