[ICNN2-04] Varifocal Meta-devices from 1D to 3D for Bioimaging and Future 6G Communication

*Jingcheng ZHANG¹, Mu Ku Chen¹, Din Ping Tsai¹ (1. City University of Hong Kong)

Meta-devices enable advanced optical and THz applications, such as bioimaging and 6G communications. we design, fabricate, and implement a dielectric Moiré metalens for fluorescence imaging. We also report the synthetic phase design of rotary doublet Airy beam and triplet Gaussian beam varifocal meta-devices to fully control the terahertz beam's propagation direction and coverage area.
