研究目的
Investigating the characteristics of terahertz plasmonic structures based on metallic wire woven meshes to support Fano resonance.
研究成果
The investigation reveals that MWWM improves the surface field of MHA for the THz wave sensing applications by enabling a large volume of resonance field and modulating the spectral properties of resonance field through the bent sections of the wires.
研究不足
The study is based on numerical calculations and lacks experimental validation. The practical implementation and scalability of the MWWM structure for sensing applications need further investigation.
1：Experimental Design and Method Selection:
Numerical simulations based on the finite-difference time-domain (FDTD) method were used to compare the transmittance spectra between the MWWM and planar metal-hole-array (MHA).
2：Sample Selection and Data Sources:
The structural period (Λ) is
3：254 mm, and the metal-wire diameter (D) is 08 mm. List of Experimental Equipment and Materials:
Perfect electronic conductor (PEC) was used as the metal.
4：Experimental Procedures and Operational Workflow:
The cells along X- and Y-axes are infinitely and periodically extended. The perfectly matched layers (PML) are occupied along the Z-axis of MWWM.
5：Data Analysis Methods:
The transmittance spectra in 0.1–1 THz were analyzed.
