AI Article Synopsis
- A double-face copper-cladded meta-hologram is developed to manipulate electromagnetic waves' amplitude in both transmission (when waves pass through) and reflection (when waves bounce back), based on the polarization of incoming waves.
- The meta-hologram successfully encodes the amplitude information of two separate images onto one surface, with experimental results matching simulation predictions.
- This innovative metasurface design improves electromagnetic wavefront control across various frequencies, addressing the limitations typically seen in traditional systems that only work within narrow frequency bands.
Article Abstract
Here, we propose a double-face copper-cladded meta-hologram that can efficiently manipulate the amplitude of electromagnetic waves in both transmission and reflection spaces, depending on the polarization state of the incident electromagnetic wave. The proposed meta-hologram is validated by encoding the transmission-reflection amplitude information of two independent images into a single metasurface. The holographic images obtained from measurements agree qualitatively with simulation results. The proposed metasurface presents a novel, to the best of our knowledge, scheme for electromagnetic wavefront control in the whole space and overcomes the limitations of narrow frequency band operation.
