Finite rank acoustic scattering problems
Copyright policy )Finite rank acoustic scattering problems
By comparing several known exact solutions of acoustic scattering problems, it is observed that the scattered fields show some joint features. The directivities which are functions of the direction of incidence and of the observation direction can be expressed in terms of one or two functions of one variable. By a type of acoustic momentum equation this is shown to be related to the occurrence of edges in the scattering region. The number of functions of one variable, which we call the rank of the scattering problem, is related to the number and type of edges.
