Resumo
Dispersion relations are investigated for a transversely inhomogeneous piezoelectric layer with attenuation. Using the complex modulus concept, the problem is reduced to a first-order matrix differential equation with complex coefficients. Characteristic structural features of dispersion relations are studied both analytically and numerically. An asymptotic analysis is performed for the low-frequency region.
