Abstract: Sensing liquids and their contaminations is very important for many applications. In this paper, the LC-resonance response of circular split rings illuminated with a normal incidence light is analyzed. The tuning response of the resonant frequency upon loading various samples of liquids is described. The liquids are deposited on the array of the rings. The sensor allows to extract various information about the dielectric properties and the loss from the resonant frequency. The analyses process consists of comparing the resonant shift to characterize the liquid type and the resonant dip to examine the impurities induced in the liquid.
