Abstract:A metamaterial sensor that can be applied to detect water content in emulsified oil is proposed, which is reusable in experiment and nondestructive to the sample. Electric field of the original absorber is researched to guide the design of microfluidics. Also, its equivalent circuit model is proposed to validate its ability as a sensor. The calculated sensitivity of the sensor is 339 MHz/ε r in the range of 11.26 GHz to 10.044 GHz, indicating its potential for detecting the emulsified oil. The experimental res… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
