To study the mechanical properties of segmented rays, my colleagues and I used theoretical models and 3D-printed fins to compare segmented rays with rays made of a non-segmented flexible material.

Metalens modulate the light field with subwavelength structure, also known as meta-atoms, offering numerous advantages such as lightweight design, ease of integration, and high controllability ...
