研究目的
Investigating the Fano resonance in a MIM waveguide with two triangle stubs coupled with a split-ring nanocavity for sensing applications.
研究成果
The proposed structure is highly promising for nanophotonic applications, with a sensitivity of 1500 nm/RIU and a high FOM of 65.2. The Fano resonance is significantly determined by the structural parameters of the sensing system.
研究不足
The study is theoretical and relies on simulations, which may not fully capture real-world conditions. The sensitivity and FOM are dependent on geometric parameters, which may limit practical applications.
