KW - Semiclassical approach, Fraunhofer diffraction, transmission amplitude.
AB - <p style="text-align: justify;">We study the transport through weakly open rectangular billiards by a new
semiclassical approach within the framework of the Fraunhofer diffraction. Based on
a Dyson equation for the semiclassical Green&#39;s function, the transmission amplitude
can be expressed as the sum over all classical trajectories connecting the entrance and
the exit leads. We find that the peak positions of the transmission power spectrum not
only correspond to classical trajectories but associate with a lot of nonclassical trajectories
and the contributions to the power spectrum of the transmission amplitude for
the first mode are largely depending on the classical trajectories with small incident
angles showing a good agreement with the diffracted angular distribution within the
framework of the diffractive scattering effect at the lead openings.</p>
