We present a resonator-based sensor for the measurement of the refractive index of dielectric liquidsamples. The proposed sensor operates on the basis of an electromagnetic resonance between a thinmetallic grating and a reflecting ground plane. The fluid whose refractive index is to be measured fills the region between the metallic grating and the ground plane and causes a considerable shift in the resonance frequency (>500 GHz/RIU). The sensor has a relatively simple structure; therefore, it can be manufactured economically on industrial scales.

Abstract-Highly sensitive terahertz dielectric sensor for small-volume liquid samples
We present a resonator-based sensor for the measurement of the refractive index of dielectric liquidsamples. The proposed sensor operates on the basis of an electromagnetic resonance between a thinmetallic grating and a reflecting ground plane. The fluid whose refractive index is to be measured fills the region between the metallic grating and the ground plane and causes a considerable shift in the resonance frequency (>500 GHz/RIU). The sensor has a relatively simple structure; therefore, it can be manufactured economically on industrial scales.
