A Meta-Material Position Sensor Based on Magneto-Inductive Waves

In this paper we report our first investigations of a new type of position sensor based on the propagation of metamaterial waves. Using knowledge of magnetoinductive waves in a one dimensional metamaterial we are able to unambiguously localise an object which impinges on the near field of the metamaterial structure. Key performance metrics are investigated and the ultimate range of the sensor is limited only by the metamaterial's quality factor.
