Mixed-Resolution High-Q Sensor Based on Hybridized Spoof Localized Surface Plasmons

Spoof localized surface plasmons (LSPs) have proven significant advantages in sensing and detection. In this work, we propose a high- Q -factor high-sensitivity hybridized spoof LSP sensor mixed-resolution algorithm. The consists of two concentric inner outer structures with corrugated rings coupled to each other. achieved is up 178, the figure merit ( FoM ) 30. Moreover, algorithm, combined multiple resonant peaks, proposed enhance . This algorithm doubles effectively. has wide range application prospects field high-frequency on-chip resonators sensors.
