Abstract:

More detailed measurements have been made on the resonance mode structure of PZT-composite plate transducers. These are compared with constant strain and constant stress versions of Floquet space harmonic theory, with good agreement. Quantitative measurement procedures for measuring bulk wave and surface wave coupling in PMN are being developed. The dependence of poled interface waveguide characteristics on fabrication parameters have been measured, and interface directional couplers have been realized. Author
