Abstract
Comments are presented on two recent papers [J. Acoust. Sec. Am. 96, 2546 (1994), J. Acoust. Sec. Am. 100, 57 (1996)]. Their results can be obtained with much economy of work by employing an alternative representation for the decomposition of the displacement. This decomposition is useful whenever transversely isotropic materials are being studied. (C) 1998 Acoustical Society of America. [S0001-4966(98)00712-7].
