Nous étudions les ondes acoustiques rayonnées par un transducteur interdigité dans le volume d'un substrat piézoélectrique. Des diagrammes de rayonnement dans des coupes de LiNbO3 sont présentés ainsi que leurs vitesses de propagation et angles du flux d'énergie. L'effet d'anisotropie sur le diagramme et le couplage entre ondes de volume et ondes de surface avec fuite sont analysés. Le critère de sélection d'une coupe selon une application particulière de ces ondes est proposé.The paper presents our calculated radiation diagrams, propagation velocities and power flow angles of deep bulk acoustic waves radiated by an interdigital transducer in several LiNbO3 substrates. Anisotropy effect on the radiation patterns and the coupling between bul...
