Abstract :
Parallel-plate waveguide sensors are investigated by characterizing TM and TE modes when filled with inhomogeneous and homogeneous samples. Effects of multi-mode TE propagation within PPW and radiation patterns are investigated. Lactose detection is demonstrated by TDS and CW-VNA techniques.
