High-Efficiency High-NA Metalens Designed by Maximizing the Efficiency Limit [PDF]

CLEO 2024, 2023
We identify optimal system parameters that maximize the upper limit of transmission efficiency and then perform inverse design to find high-NA wide-field-of-view metalenses with a record-high efficiency (98% transmission, 92% Strehl ratio, NA = 0.9).

Stiffness Modeling of Tooth Interior Fatigue and Tooth Flank Fracture and Their Fault Characteristics in Electromechanical Coupling Systems

Shock and Vibration
Tooth flank fracture (TFF) and tooth interior fatigue fracture (TIFF) usually occur on case-harden gears in electromechanical coupling systems, both starting from the core caused by metal fatigue. The cracks propagate rapidly compared with the total life
