This study reviews surface acoustic waves (SAW) and pseudo-surface acoustic waves (PSAW) in piezoelectrics. It presents a matrix method for calculating PSAW properties, aiding in the search for optimal materials for device applications.

Area of Science:

  • Acoustics and Materials Science
  • Solid State Physics
  • Electrical Engineering

Background:

  • Pseudo-surface acoustic waves (PSAWs), also known as leaky SAWs, have been studied for over 25 years.
  • Exploitation of PSAWs in piezoelectric devices has increased since the 1970s due to their high velocities and electromechanical coupling.
  • There is a need for efficient methods to calculate PSAW properties for material selection.

Purpose of the Study:

  • To review the fundamental characteristics of surface acoustic waves (SAW) and pseudo-SAWs (PSAW) in piezoelectric materials.
  • To present a matrix method for formulating boundary value problems for SAW and PSAW modes.
  • To derive computationally simple, frequency-independent analytical functions for calculating PSAW properties.

Main Methods:

  • Formulation of mechanically free, open-circuited, and short-circuited surface wave boundary value problems for piezoelectrics using the matrix method.
  • Description of both SAW and PSAW modes.
  • Derivation of analytical functions for calculating attenuation per wavelength (alphalambda), phase velocity (v(p)), and electromechanical coupling (K(2)).

    • Main Results:

    • Computationally simple, frequency-independent analytical functions were derived for calculating alphalambda, v(p), and K(2) for any direction on any material plane.
    • The relationship between these functions and the effective permittivity concept was demonstrated.
    • Numerical examples showed that low-loss orientations for PSAWs are highly sensitive to material constant values.

    Conclusions:

    • The matrix method provides a clear framework for analyzing SAW and PSAW properties in piezoelectrics.
    • The derived analytical functions facilitate the calculation of key PSAW parameters, aiding in material discovery.
    • Understanding the sensitivity of low-loss orientations to material constants is crucial for designing effective piezoelectric devices.
