Metamaterials in microwave sensing applications

Metamaterials are artificial structures that have some unique properties suitable for a wide range of sensing applications. Based on these structures we have developed different types of sensors, using combined right/left-handed (CRLH) metamaterial transmission lines (TL). A cylindrical mass flow sensor and two types of planar sensors for position detection are presented. The area of application of these prototypes is industrial processes, where the sensing and control of all tasks involved in a system is crucial for a successful performance. All the sensor prototypes are analyzed and tested in dedicated measurement setups to proof the concepts.
