Abstract

A new spectrum of electromechanical properties are realized with composite materials made by combining a piezoelectric ceramic and a passive epoxy. we have studied disks of rod composites in which the epoxy resin holds together parallel thin rods of piezoelectric ceramic oriented perpendicular to the faces. If the lateral spatial periodicity of the structure is smaller than all the relevant acoustic wavelengths, these composites behave as a homogeneous piezoelectric with new "effective' material parameters. For ultrasonic transducer applications we can engineer the structure to make materials whose electromechanical coupling is higher and acoustic impedance is lower than those of conventional piezoelectric ceramics.
