Ce mémoire présente les recherches effectuées sur une nouvelle méthode de transduction, exploitant la propagation des ondes à haute fréquence, pour la détection de polluants atmosphériques. Dans un premier temps, les principaux modes de transduction exploités dans les capteurs existants sont présentés. Ils fonctionnent dans des gammes de fréquences différentes des microondes, afin de comprendre ce que peut apporter cette nouvelle transduction. La permittivité diélectrique est le principal paramètre physique responsable de la détection microonde. Cependant, la variation de la conductivité du matériau sensible modifie également la transmission de l'onde à travers le dispositif microonde. Les propriétés de propagation d'une onde sont formulées...
