The characteristics of an electromechanical transducer are expressed in a distributed-parameter basis without using any lumped-parameter components. Two energy modes, elastic mode and dielectric mode, are considered, which interact with each other in some mathematical regularities. Physical processes on the two modes are represented with some matrix operation, and the infinite geometric series of the matrices, reflecting the boundary conditions of transducer, provides frequency characteristics from the viewpoint of locally stored energy in the transducer. The sum of the local characteristics provides the global characteristics of the transducer. The energy transfer and the shift of resonance frequency owing to the electromechanical coupling can be calculated by this method.
