Terahertz radiation field distribution manipulation gains increasing attention from both science and technology, but available mechanisms are hard to implement it. We design two asymmetric double-split ring resonators (DSRRs) based on theoretical analysis to realize terahertz radiation field distribution manipulation by metasurface with graphene substrate. Here we show that in principle the dynamic intensity regulation of left-handed circularly polarization (LHCP) and right-handed circularly polarization (RHCP) components can be realized by satisfying certain condition, which is derived from electro-optical effect of graphene in terahertz region. Furthermore, we show that the spatial angle control of LHCP and RHCP components can be realized by designing the arrangement and combination of meta-atoms based on Pancharatnam-Berry (PB) phase. Terahertz radiation field distribution manipulation not only promotes the sensing of terahertz micro-devices, but also facilitates the multifunctional control of holographic projection.
