This paper is devoted to study one of the most important applications of metamaterials based on Split Ring Resonator (SRR) which is thin-film sensing and sensing liquids properties. We provide a broad overview of thin film deposition methods, depositing the substance material in the gap, under the rings or on 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. Split rings accommodate a wide range of individual preferences and sensing abilities. We demonstrate sensing features of rectangular split rings designed to resonate in the frequency range of 8-12 GHz.
