  Simulation of Electron Transport through two dimensional(2D) waveguide using
Quantum Transport Boundary Method (QTBM) is done. Specifically, as an example
the results of modeling L-shaped contact for a rectangular waveguide are
presented. 2D-QTBM approach can be used in any scenario where the vertical axis
of the device structure is significantly large and therefore the 2D
approximation would be considered valid. This method elegantly generalizes to
arbitrary shaped waveguides.
