To study the ballistic transport of charge carriers in nano-structured quantum devices, a highly efficient numerical technique is developed, which provides continuous transmission spectra for arbitrarily complex potential geometries in two dimensions. We apply the proposed method to single and double barrier structures and compare the results with those obtained using standard techniques for computing transmission coefficients. Excellent numerical agreement as well as considerable computational saving is demonstrated.
