title: Dependency of resonance frequencies and effective coupling coefficients of piezoceramic rectangular bars and plates on aspect ratio.
abstract: The resonance frequencies and effective coupling coefficients of piezoceramic rectangular plates polarized through their width and transversely polarized bars are presented as functions of their lateral aspect ratios. The results are obtained by employing the coupled vibration analysis technique that was previously illustrated for rectangular plates polarized through the thickness [J. Acoust. Soc. Am. 126(6), 2983-2990 (2009)]. The results of calculations show good agreement with experimental data. Conclusions are made on preferable values of the aspect ratios in terms of the effective coupling coefficients.
