研究目的
Investigating the therapeutic effects of a specific herbal medicine on a particular disease.
研究成果
The proposed plasmonic structure demonstrates excellent nano-sensing performance with a great sensitivity of 1200 nm/RIU and an ultra-high maximal figure of merit (FOM) value of 3.0 × 106. The structure's flexibility and malleability make it suitable for highly integrated photonic circuits and optical devices.
研究不足
The technical and application constraints of the experiments, as well as potential areas for optimization, are not explicitly mentioned in the abstract.
1：Experimental Design and Method Selection:
The study employs a simple plasmonic structure made up of a metal baffle in the middle of the metal–insulator–metal (MIM) waveguide coupled with an isosceles triangular cavity to achieve triple Fano resonances. The finite element method (FEM) is used for numerical calculations. The multimode interference coupled mode theory (MICMT) and the standing wave theory are used for analyzing the Fano resonances phenomenon.
2：Sample Selection and Data Sources:
The samples are theoretical models of the plasmonic structure, with parameters such as the height of the isosceles triangular cavity (h = 565 nm), the base of the triangular resonator (b = 370 nm), the thickness of the baffle (t = 10 nm), and the coupling distance between the baffle and the triangular resonator (g = 10 nm).
3：List of Experimental Equipment and Materials:
The study uses COMSOL Multiphysics software for numerical simulations.
4：Experimental Procedures and Operational Workflow:
The transmittance spectrum is numerically studied by the FEM with scattering boundary conditions in COMSOL Multiphysics software.
5：Data Analysis Methods:
The MICMT is used for explaining the transmission property, and the standing wave theory is used to calculate the resonant wavelengths.
