Can Scattering Matrix associated with the light scattering in a thin tissue assumed to be a unitary matrix. Is this assumption valid ?
Just as we try to produce a collimated light by using two spherical lenses can we collimate a light into a line by use of two cylindrical lenses ? So that it remains a line of same length for a...

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...
