| description | The invention discloses a polarization selection response non-Hermite metasurface which comprises six metasurface arrays, each metasurface array performs polarization selection response on incident waves and radiates reflection waves in a preset polarization state, each metasurface array comprises 4 * 4 metasurface units arranged in an array mode, and the metasurface units are arranged in the array mode. The metasurface unit comprises a metal structure layer, an intermediate dielectric layer and a metal reflecting layer from top to bottom, and the metal structure layer comprises a metal structure for regulating and controlling the amplitude and phase of a reflected wave of the metasurface unit; and the metal structure layers of the metasurface units in the six metasurface arrays respectively comprise four nanorod type metal structures with different orientations and two F-like metal structures with mirror symmetry. According to the invention, six kinds of polarization selection responses are carried out on re |
