Abstract
A simple expression of the electric conductance through a
nanostructure connected to 2 electrodes is obtained by using the
phase-shift analysis. The phase-shifts are given by solving the
characteristic equation obtained by extending the method applied to
the single impurity problem in the metal. It is shown the importance
of the effect due to multiple orbitals in nanostructures. Concrete
examples of the conductance through some bridge systems are given.
