Who can explain the following questions about transfer matrix?

formula (31) in New Journal of Physics, Vol.12 123020.
[http://iopscience.iop.org/1367-2630/...12_123020.pdf]
is different from the result of another
paper in Journal of Physics:Condensed matter (Vol.21, 045305 (2009))[http://iopscience.iop.org/0953-8984/..._4_045305.pdf].
The expression for transfer matrix is different from each other, even if for a single trench.

Who can give me a hint or instruction?
