Abstract Acoustic wave propagation through an inhomogeneous medium may lead to undergo substantial
modification. This paper proposed a Green’s functions-based method for the simulation of wave propagation
through inhomogeneous medium waveguides. Under ideal conditions, a modified wave equation is derived
by variable transformations, in which only the wave speed varies with spatial coordinates. Based on the
modified wave equation the acoustic Green’s functions are derived. Then, the localized method of
fundamental solution (LMFS) in conjunction with the acoustic Green’s functions is introduced to solve the
modified wave equation. In the LMFS, the acoustic Green’s function is considered as its basic function… More >
