Notes: Abstract A simple numerical method for solving a two-terminal quantum electronic waveguide problem is presented. The method can be adapted to a quantum wire cavity of irregular geometry and/or non-constant potential field. We compare the circular bend wire with parabolic confining potential profile to the commonly used hard wall confinement. We find an energy scaling which makes the results correspond closely.
