Abstract
Meta-devices, which are advanced optical elements composed of meta-atoms engineered at the sub-wavelength scale, have garnered significant attention from researchers due to their ability to manipulate the characteristics of incident electromagnetic waves. However, conventional meta-devices, primarily consisting of a single type of meta-atom, suffer from an intrinsic lack of freedom, which in turn restricts their performance and limits their application potential. An integrated resonant unit (IRU) has emerged as a promising solution. It combines multiple meta-atoms, resonant modes, and functionalities into a supercell, can achieve responses and functionalities that exceed those of conventional meta-atoms. This talk will first illustrate the concept of IRUs and then employ two different types of IRUs, plasmonic and dielectric, to demonstrate their ability that break through the phase compensation limitations and improve working efficiency for enhancing achromatic focused beam generation.
