New microwave gas detector using dielectric resonator based on a Whispering-Gallery-Mode

Résumé

This work describes a novel concept of gas sensor based on RF-transduction technique. The sensor uses a millimeter-wave planar dielectric resonator operating with Whispering-Gallery-Modes. The dielectric resonator incorporates a sensitive material (TiO2 or SnO2) and two coplanar waveguides coupled to its input and output. In presence of gas, the dielectric permittivity of the resonator is modified and the resonant frequencies of some Whispering-Gallery-Modes are then significantly changed. The proof of concept is demonstrated here, through full wave electromagnetic simulations.
