Near Field Scattering from an Object in a Waveguide with Applications.(Reannouncement with New Availability Information)

摘要

The computation of scattered fields from fluid-loaded bounded objects condition(EBC) or T-matrix method for electromagnetic, elastic, and acoustic problems. We outline the general principles of the EBC method along with vital structural and computational improvements. Our principle objective is to construct the near field due to the scattering of a guided wave from a target in a waveguide. We then apply the method to problems of physical interest which pertain to acoustical scattering from submerged three dimensional elongated impenetrable objects or elastic solids and shells. Several physical examples of interest are offered and interpreted.... Acoustic scattering, Shallow water, Waveguide propagation.
