This study investigates wave propagation characteristics when guided waves propagate in a waveguide surrounded by non-homogeneous media. Assuming that the medium consists of same size elements, the acoustic properties of each element were determined using SWFEM method. The boundary conditions of each element and the waveguide were determined by random number.
