摘要
The phase responses of the adopted resonating meta-atoms typically exhibit Lorentz-like frequency dispersion, therefore such metadevices can usually work only at a narrow band frequency. Here, we design and fabricate a metasurface composed of silicon posts for the terahertz frequencies in transmission mode, and we experimentally demonstrate achromatic Airy beams and achromatic focusing.
