A periodic array of extruded nanoprisms is proposed to generate surface plasmon resonances for sensing applications. Nanoprisms guide and funnel light towards the metal-dielectric interface where the dielectric acts as the medium under test. The system works under normal incidence conditions and is spectrally interrogated. The performance is better than the classical Kretschmann configurations, and the values of sensitivity and figure of merit are competitive with other plasmonic sensor technologies. The geometry and the choice of materials have been made taking into account applicable fabrication constraints.
提出了一种周期性排列的挤压纳米棱镜阵列，用于产生表面等离子体共振以实现传感应用。纳米棱镜将光引导并汇聚到金属 - 电介质界面，在该界面处电介质作为被测介质。该系统在正入射条件下工作，并进行光谱检测。其性能优于传统的克雷奇曼配置，灵敏度和品质因数的值与其他等离子体传感器技术具有竞争力。在设计几何结构和选择材料时已考虑到适用的制造限制。
