“…In addition, inducing the chirality of top plasmonic nanostructures provides an alternative way to obtain polarization-sensitive light-absorption in the biosensing of chiral molecules and analytes [25][26][27][28][29][30]. To date, a series of narrowband perfect absorbers based on MIM nanostructures have been demonstrated across different frequency ranges [31][32][33]. To meet the complex requirement of biosensing or environment detection applications, the flexible adjustment of two or more absorption narrowbands is needed, which has always been a challenge in the visible and near-infrared spectral range.…”

Plasmonic nanostructures as narrowband perfect absorbers have garnered significant attention due to their potential applications in biosensing and environment detection. This study emphasizes the investigation of arrayed split ring nanostructures within the configuration of metal-insulator-metal (MIM) multilayers, resulting in a maximum light absorption of 99.94% in the near-infrared (NIR) spectral range. The exceptional absorption efficiency of the device is attributed to the strong resonance of electric and magnetic fields arising from the Fabry–Pérot cavity resonance. The resonant peak can be flexibly tuned by engineering the dielectric layer thickness, the period, and the geometric parameter of split rings. Remarkably, the device exhibits promising capabilities in sensing, demonstrating a sensitivity of 326 nm/RIU in visible wavelengths and 504 nm/RIU in NIR wavelengths when exposed to bio-analytes with varying refractive indices. This designed nanostructure can serve as a promising candidate for biosensors or environmental detection.

“…In 2022, Jiabao Jiang designed a surface plasmon resonance sensor based on the metal-dielectric-metal (MDM) structure, which is composed of AU gratings and Al2O3 gratings. The maximum sensitivity can reach 362nm/RIU [10] . Most of the above-mentioned SPR sensors can only conduct high-sensitivity detection in a single environment and lack strong adaptability to the environment.…”

In this article, a new three-dimensional multi-layered nanoscale elliptical cylinder structure-based surface plasmon resonance sensor is designed, which utilizes the nite difference time domain method and FDTD simulation software for numerical simulation. The top of the structure is an elliptical cylinder array attached to a gold lm with nanoholes. The middle layer is a dielectric layer, which can restrict the electromagnetic eld. The bottom layer is an Au lm and Si substrate. Surface plasmon resonance is excited by a vertically incident plane wave structure, and the incident electromagnetic wave is coupled to local surface plasmon through gold nanoscale elliptical cylinders. By adjusting the relevant structural parameters, the structure's resonance wavelength and resonance depth can be well adjusted. The optimized sensing structure has a smaller half-width than the traditional solid elliptical cylinder, higher sensitivity, and a larger quality factor. This structure can detect refractive indices in both gaseous and liquid environments, overcome the disadvantage of only being able to sense in a single environment, and provide a new approach for surface plasmon resonance sensing in biology and chemistry.
