英文摘要 | Recently, terahertz (THz) wireless communication has been widely investigated as the future prospect of wireless network architecture. However, most of the natural existing materials are inapplicable for THz devices, which hinder their further development. To promote the integration and channel capacity of the THz wireless communication systems, an ultrabroadband polarization conversion metasurface for efficient multi-functional wavefront manipulation is proposed. The designed metasurface is composed of an arrow-type structure sandwiched by a pair of orthogonal gratings, which can induce the Fabry-Perot-like cavity for improving the transmission. Simulated results indicate that the transmission coefficient of the cross-polarization metasurface is higher than 90% from 0.73 THz to 2.24 THz, and the corresponding polarization conversion ratio is greater than 99.5%. Moreover, the phase coverage of 0-2 pi at operation frequency can be easily obtained by altering the geometric parameter of the metasurface. To demonstrate the concept of wavefront manipulation, anomalous refraction, focusing metalens, and vortex beam generation are investigated in detail. All of these applications exhibit a remarkable performance of the proposed metasurface that has great potential in prompting the efficient, broadband and compact systems for THz wireless communication. |
