Meta-device is a new type of flat optical device composed of artificial nanostructures that can manipulate the incident electromagnetic wave's phase, polarization, and amplitude. We developed varifocal meta-lenses to manipulate the focusing spot in 1D for bioimaging in 2D and 3D for 6G communication.
