Surface Plasmon Near Field Effects in Silver Nano Cylinders Arranged in Triangular Geometry

A dual functional asymmetric plasmonic silver nanostructure for temperature and magnetic field sensing

“…PDMS is a polymer material possessing good mechanical properties, easy processing, and high thermo-optic coefficient. The RI of PDMS varies with temperature according to the following relation: 37 n PDMS = (k  T) + 1.4176 (2) where k = À4.5  10 À4 1C À1 is the thermo-optic coefficient of PDMS and T is the measured temperature in 1C. As the temperature increases, n PDMS decreases.…”

“…Localized surface plasmon resonance (LSPR)-based sensors, enriched in tunability of light-matter interaction and sensing performance, are of significant interest and are the core of sensing applications. [1][2][3][4] Modulating the plasmonic resonance of structures with geometric asymmetry boosts the performance and enables the accurate detection of ultra-small changes of external entities such as physical and chemical properties in close vicinity to the structure. Plasmonic nanostructure arrays with high uniformity and site-selective sensing approaches were detailed in previous works both experimentally and theoretically.…”
