Dual-channel additive compensation of mask-plane illumination uniformity for i-line lithography

Runqi Zhou, Lixin Zhao, Yu He

To satisfy the requirement of two-dimensional (2D) uniformity for rectangular flat-top illumination at the mask plane in i-line projection lithography, this paper proposes a dual-channel additive ultraviolet illumination compensation method. The system comprises a main homogenized illumination channel and an independent compensation …

Gauge-Tunable Uniform Delocalization of Higher-Order Topological Photonic Modes

Shiqi Li, Yu He, Yunlang Wang, Shiyin Jia et autres

Higher-order topological photonic systems typically host corner states that are exponentially localized. Here we uncover a distinct regime of uniformly delocalized higher-order topological modes, emerging from the interplay of multiple spatially varying Dirac mass terms under chiral symmetry. These modes exhibit uniform …

Superionic inner core and anisotropic structure driven by geomagnetic field

Yu He

Seismological observations suggested that Earth’s inner core presents complex heterogeneity and anisotropic structure. The key to understand the structure of Earth’s inner core is to study the mineralogical composition and dynamic mechanism of the anisotropic structure of Earth’s inner core. Hexagonal close-packed …
