Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index
Advanced Photonics Research, EarlyView.Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

Real‐Time In Vivo Cellular‐Level Imaging During Puncture
Advanced Science, EarlyView.We present an artificial‐intelligence‐empowered integrative‐light‐field microendoscopy (AIM) needle that delivers real‐time in vivo, diffraction‐limited cellular‐level imaging during puncture and visualizes layered microstructures along the needle path. As a microscopic complement to CT/ultrasound, it improves sampling localization and adds preliminary
