In this paper, we outline the construction of Maple routines for the solution of the Helmholtz equation V2~b + k2~2 -~ 0 with Dirichlet boundary conditions in two-dimensional domains. By means of the symbolic manipulator, we are able to perform a numerical study of the eigenvalues for quantum billia

The wavenumbers and eigenmodes of an infinite cylindrical dissipative silencer of arbitrary cross-section are determined by using the null-field approach. This analytical technique provides an alternative to the numerical variational formulations used in the literature so far. The rate of convergenc
