WAVE DIODE BASED ON DEFORMATION OF THE PROPAGATION ENVIRONMENT

摘要

The invention relates to a mechanical diode device (MECADIODE) for transmitting a mechanical wave between a first pole (P1) and a second pole (P2), said device (MECADIODE) comprising a first transducer (T1) coupled to said first pole (P1). a second transducer (T2) coupled to said second pole (P2), a first volume (V1) adjoining said first pole (P1) and comprising a first material (M1), a second volume (V2) adjoining said second pole (P2) and said first volume (V1) and comprising a second material (M2), a surface (SINT) junction substantially planar between said first and second volumes (V1, V2), said SINT surface being oriented perpendicular to a defined axis (L1) by respective positions of said first and second poles (P1, P2) in said device (MECADIODE), said mechanical device being characterized in that said first material (M1) and second material (M2) delimited by said surface (SINT) present respect ZM1 and ZM2 mechanical impedances whose ratio is greater than a predetermined threshold value.
