Acoustic (Fluid-Fluid) Multiple Scattering Theory (MST) in MATLAB

Multiple Scattering Theory (MST) is implemented in MATLAB and used to:

1. Calculate the total acoustic field following interaction between a 2D incident, planar background wave and a cluster of 2D circular scatterers. The resultant field is plotted.

2. Calculate a pressure spectrum at a point in a 2D field following interaction between a 2D incident, planar wave and a cluster of 2D circular scatterers. The resultant spectrum is plotted.

Both the background and scatterer media are fluids and longitudinal waves are considered.
