Design and optimization of a compact dual band metal insulator metal filter for high sensitivity refractive index sensing using particle swarm optimization

Abstract This paper presents a highly optimized metal-insulator-metal (MIM) filter designed for لrefractive index sensing applications, with dual cut-off bands at 1008 nm and 1348 nm. The filter’s dimensions are optimized using the Particle Swarm Optimization (PSO) algorithm, ensuring maximum sensit...
