Faran model solution
The “Faran model” refers to a classic solution to an imporant acoustics problem: the scattering of sound from elastic cylinders or spheres in an elastic medium under plane-wave insonification. This model has many applications in acoustics research.

This code uses numerical methods for portions of the solution that do not have closed-form solutions or standard Matlab function calls. Its precision provides good apparent agreement with published polychromatic solutions. Validation code is included to test the code installation and to demonstrate this agreement. The author welcomes bug reports and suggestions for refinements.
