| Abstract |
A junction of N semi-infinite cylindrical acoustic waveguides is considered. The asymptotics of the scattering matrix is constructed for small frequencies. The effects of almost complete reflec
tion and complete transmission of waves are found only in the cases N = 1 and N = 2 under condition
of equal cross section areas, while for other cases, there are no anomalies of the wave diffraction. |
