Are Transfer and Scattering Matrices Useful Without Knowledge of H?

[hokhani]

To my knowledge, to have Transfer matrix or Scattering matrix one has to solve Schrödinger equation so I don't know how these concepts are useful!

If you want to use it for a series of planar thin films, there is freely available MATLAB code from these guys: http://onlinelibrary.wiley.com/doi/10.1002/adma.201000883/abstract
Have a look at the paper to see if that's the kind of thing you need it for and if so, I think the code is somewhere on the group's website.

Especially solve Shrodinger equation without knowing H :)
