摘要：
A high-Q sensor based on hybridized spoof localized surface plasmon (LSP) has proved to be advantageous in detection and sensing. The sensor is composed of three concentric inner, middle, and outer LSP structures with corrugated rings coupled with each other. Through multiple hybridizations of spoof LSP, the maximum simulated Q-factor of the sensor is up to 414, and the sensitivity is up to 1.47 GHz<middle dot>RIU-1. To validate the proposed sensor design concept, a prototype of the sensor with three layers is fabricated and measured, the measured results are in agreement with the simulated ones.
