| description | The invention provides an elastic wave intensifier based on a heterojunction structure, and belongs to the technical field of elastic wave regulation and control, the elastic wave intensifier comprises an elastic wave heterojunction, and the elastic wave heterojunction realizes elastic wave signal enhancement in the heterojunction. The elastic wave intensifier based on the heterojunction structure further comprises a first structure and a second structure which have periodic fluctuating elasticity and are different in structural parameter, and the elastic wave heterojunction is arranged between the first structure and the second structure. The two sections of fluctuating first structures and second structures can transmit elastic wave signals and have different transmission characteristics. The elastic wave intensifier based on the heterojunction structure can be adjusted according to an actual application scene, and the height of the incident surface of the first structure or the emergent surface of the seco |
