A re-expansion method for determining the acoustical impedance and the scattering matrix for the waveguide discontinuity problem
The paper gives a new method for analyzing planar discontinuities in rectangular waveguides. The method consists of a re-expansion of the normal modes in the two ducts at the junction plane into a system of functions accounting for the velocity singularities at the corner points. As the new expansio...
