Applications of Resonant Microwave Sensors

This seminar will look at the interdisciplinary uses of resonant microwave sensors. After introducing the basic principles, their use in the determination of fundamental electronic properties of materials at microwave frequencies will be discussed. Two examples will be considered, namely the characterisation of carbon nanotubes, and new types of transparent conductors. The same types of resonators also have many potential applications and the second part of the talk will look at two particular sensors. The first is in the area of microfluidics, where very accurate dielectric measurements of tiny amounts of fluid are possible. The second is in the area of medical devices, where a new type of non-invasive blood glucose meter has been developed.
