Dispersion characteristic of ultrathin terahertz planar lenses based on metasurface
چکیده انگلیسی
Terahertz (THz) radiation has attached a lot of attention due to its potential applications. The smart optical components will greatly boost the application of the THz technology. Ultrathin planar lenses which can greatly reduce the thickness of the components are designed and fabricated in the THz region based on the metasurface. The dispersion characteristic of this kind of ultrathin planar lenses is systematically investigated. It is demonstrated that the focal lengths of the proposed lenses become shorter with the wavelength of the illuminating light increasing. Moreover, the ultrathin planar lenses perform a good focusing characteristic over a broad wavelength range. The results help us to further understand the optical properties of the lenses based on the metasurface and provide a considerable important reference for its future applications in miniaturization and integration of the THz system.
