Title: Transducteur d'ondes de surface unidirectionnel.
Inventor: PIERRE DUFILIE
IPC: H03H9/145
Filed: 1989-10-20
Abstract: L'invention concerne les transducteurs pour ondes de surface Elle consiste à utiliser une succession alternée de cellules émettrices (E) et réflectrices (R). Les cellules émettrices émettent à gauche (43) et à droite (44) des ondes de surface en opposition de phase. Les cellules réflectrices ont un coefficient de réflexion qui est en opposition de phase entre la gauche (53) et la droite (54). Les ondes émises (61) par les cellules émettrices interfèrent avec les ondes (62, 63) réfléchies par les cellules réflectrices (R1 , R2 ) de manière destructrice dans un sens et de manière constructive dans l'autre sens. Elle permet de réaliser des transducteurs à ondes de surface unidirectionnels avec des espacements égaux à lambda/4 et lambda/6 seulement.
