报道了一种基于超表面诱导相位不连续的宽带太赫兹波偏转器。偏振方向与入射方向正交的0.43 ~ 1.0太赫兹的各种频率分量被偏转到25 ~ 84的宽角度范围内。因此，从光束偏转器发展的菲涅耳带板能够聚焦宽带太赫兹辐射。
A broadband terahertz wave deflector based on metasurface induced phase discontinuities is reported. Various frequency components ranging from 0.43 to 1.0 THz with polarization orthogonal to the incidence are deflected into a broad range of angles from 25 to 84. A Fresnel zone plate consequently developed from the beam deflector is capable of focusing a broadband terahertz radiation.
