Modeling of Coulomb coupling and acoustic wave propagation in LiNbO3
چکیده انگلیسی

The angular spectrum propagation technique is applied to modeling of wave propagation through piezoelectric media. The calculations of the angular spectrum propagator are based on the relevant equation for the slowness surface resulting from the solution of the Christoffel equation with piezoelectrically stiffened elastic constants. A two-dimensional FFT algorithm is applied in the final field superposition. We concentrate on the case of Coulomb coupling through local electrical point contacts on both the excitation and detection side. To model that case we superpose solutions for acoustic Green’s functions of different propagation modes convoluted with equivalent distributed effective sources. Calculated results are in good agreement with the measured ones.
