Polarization-dependent metalens with flexible and steerable bifocal spots
Results in Physics, 2023 Lenses are an important part of modern optical systems. We propose metalenses with bifocal spots, which realizes the beam focusing with controllable intensity ratio and free deflection of the bifocal spots.

Design of Fast Steering Mirror Based on Displacement Amplification Mechanism
Shanghai Jiaotong Daxue xuebao, 2021 According to the current situation that the deflection angle of the piezoelectric ceramics direct drive fast steering mirror (FSM) is restricted by small elongation of piezoelectric ceramics and the large deflection angle cannot be realized, a novel ...

Light bending in F[g(□)R] extended gravity theories
Physics Letters B, 2018 We show that in the weak field limit the light deflection alone cannot distinguish between different R+F[g(□)R] models of gravity, where F and g are arbitrary functions.
