研究目的
Investigating the broadband high-efficiency cross-polarization conversion and multi-functional wavefront manipulation based on chiral structure metasurface for terahertz wave.
研究成果
The proposed CSM achieves broadband high-efficiency cross-polarization conversion and multi-functional wavefront manipulation in the terahertz region. It demonstrates the potential for applications in wavefront control and communication, overcoming the limitations of previous transmission-type metasurfaces.
研究不足
The study is based on numerical simulations, and practical implementation may face challenges in fabrication precision and alignment of the tri-layered structure.
1：Experimental Design and Method Selection:
The study employs a tri-layered chiral structure metasurface (CSM) composed of two orthogonal metal wires sandwiched with a square split-ring resonator (SRR) structure. The design leverages the Fabry-Perot-like cavity-enhanced effect for broadband and high-efficiency cross-polarization conversion.
2：Sample Selection and Data Sources:
Numerical simulations are conducted using the finite integration technique (FIT) in CST Microwave Studio.
3：List of Experimental Equipment and Materials:
The dielectric substrate is polyimide with a permittivity of
4：5 and a loss tangent of 0027, and the metallic structure layers are copper films with a conductivity of σ = 8 × 107 S/m. Experimental Procedures and Operational Workflow:
The study involves designing the CSM, simulating its performance, and analyzing the results for cross-polarization conversion and wavefront manipulation.
5：Data Analysis Methods:
The performance is evaluated based on the cross-polarization transmission coefficient and the ability to achieve complete 2π phase coverage.
