    摘要: An elastic waveguide, for propagating acoustic waves, consists of an elongated solid core region and an elongated solid outer cladding region. The acoustic waves propagate in a mode where the principle particle displacement is substantially parallel to the longitudinal axis of the waveguide, this mode is called longitudinal mode. The material densities and the bulk shear wave velocities of the core and cladding region are substantially the same but the bulk longitudinal wave velocity of the cladding region is larger than that of the core region.
