研究目的
To report a new double-pointed optical antenna and its enhancement effect in the longwave infrared (LWIR) spectral regime, comparing it with single-pointed and bow-tie antennas.
研究成果
The double-pointed optical antenna demonstrates higher E-fields in the LWIR regime compared to single-pointed and bow-tie antennas, with valid RLC modeling and Fano interference in coupled configurations, suggesting potential for enhancing LWIR photodetectors in sensing and imaging applications.
研究不足
The study is based on numerical simulations, which may not fully capture real-world experimental variations or material imperfections. The RLC model is simplified and may have limitations in accuracy for all antenna configurations. Application is focused on LWIR spectral regime, potentially limiting generalizability to other wavelengths.
1：Experimental Design and Method Selection:
Numerical simulations using CST's Microwave Studio? to analyze the double-pointed optical antenna, with comparisons to single-pointed and bow-tie antennas. Theoretical modeling using an RLC circuit model for resonant frequency calculation.
2：Sample Selection and Data Sources:
Simulated antenna structures made of gold (Au) on a GaAs substrate, with specified dimensions (e.g., thickness 30 nm, lengths Ld and L, width W). Data generated from simulations.
3：List of Experimental Equipment and Materials:
CST's Microwave Studio? software for electromagnetic simulations. Materials include gold for the antenna and GaAs for the substrate.
4：Experimental Procedures and Operational Workflow:
