A STUDY OF WAVE-PROPAGATION IN VARYING CROSS-SECTION WAVE-GUIDES BY MODAL DECOMPOSITION .2. RESULTS

The full derivation of the equations governing the generalized impedan ce matrix Z, the pressure, and the velocity were presented in Part I o f this series [Pagneux et al., J. Acoust. Sec. Am. 100, 2034-2048 (199 6)]. Here only the results of that paper, i.e., the final set of equat ions which needed to be solved are repeated. Other factors influencing the solution are the boundary conditions at the end of the waveguide: Source and radiation conditions are also presented. Finally, the deta ils of the numerical implementation are also relevant, and will be dis cussed in some detail. (C) 1997 Acoustical Society of America.
