The invention discloses a phase modulation unit and a radiation system. The phase modulation unit comprises a first substrate, a second substrate, a patterned metal layer, a first electrode, a second electrode, a driving element and a liquid crystal layer. The patterned metal layer is disposed on a first surface of the first substrate facing the second substrate and includes a slotted hole, an annular groove surrounding the slotted hole and a metal ring located in a central region of the slotted hole, and the slotted hole and the annular groove expose a portion of the first surface. The first electrode and the second electrode are arranged on the second surface, facing the first substrate, of the second substrate. The driving element is connected with the first electrode and the second electrode. The liquid crystal layer is arranged between the first substrate and the second substrate. 本发明公开一种相位调制单元以及辐射系统，其中该相位调制单元包括第一基板、第二基板、图案化金属层、第一电极、第二电极、驱动元件以及液晶层。图案化金属层设置于第一基板面对第二基板的第一表面上，并包括槽孔、围绕槽孔的环形槽以及位于槽孔中央区域的金属环，其中
