| description | Reconfigurable intelligent metasurface (RIS) is a new type of artificial electromagnetic metamaterial, which can control the frequency, amplitude, phase, polarization, propagation direction and wave type of electromagnetic wave flexibly.In the field of wireless communication, RIS can be used to reconstruct the wireless communication channel to achieve blind coverage of wireless signals and improve the communication quality.First, the development and research status of RIS, the key technologies and application scenarios of RIS were summarized and analyzed.Then, a new passive RIS was proposed to realize the characteristics of the aperture reconfiguration and beam reconfiguration through passive coding and splicing principle, which had the advantages of low cost, low power consumption and low complexity.Finally, the blind area coverage enhancement experiment of indoor wireless signal based on passive reflection metasurface was carried out.The effectiveness of passive splicing metasurface in wireless communication blind coverage scenarios was proved by comparison between simulation and field measurement.In addition, for 5G/6G millimeter wave communication, the passive RIS with double-layer cross dipole elements was designed and applied to typical indoor L-shaped corridor scene to verify the enhancement effect of indoor wireless signal coverage. |
