Two-Dimensional Radiation and Scattering At Short Wave Length
The problem of radiation and scattering by objects in the case when the wave length is much smaller than the characteristic dimension of the radiator or scatterer is investigated. The boundary element method is used with the goal of obtaining accurate results in an efficient computational scheme for wave lengths less than 5 percent of the object characteristic dimension. With a systematic application of conventional boundary element techniques it is found that the modelling of such problems leads to excessive computation time due to the large number of elements, demands on Gaussian Quadrature evaluation of the fundamental solution, and the resulting large nonsymmetric matrix equation.
