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 to 
construct the approximate solution at a certain node by using some of its adjacent nodes instead of the whole 
discretization nodes. Finally, the feasibility and accuracy are demonstrated by some numerical examples 
including acoustic propagation in marine environments.},
