Implementation of the boundary integral method for electromagnetic scattering problems with geometrical discontinuities

“…To validate this model, the scattering of Gaussian impulse by an unit sphere is solved. The results are compared with Schlemmer results [2], showing good agreement (see Fig. 3).…”

“…Semidiscontinuous elements are then successfully used, and the functional nodes are moved away from the edge. In [2], Schlemmer chooses same elements for the time domain boundary integral method and uses an interpolation between the functional node and the discontinuity line. In [3], Rego implements these elements and uses specific interpolation function.…”

Implementation of the boundary integral method on MIMD systems for electromagnetic scattering problems

“…This formulation may be seen as the frequency-domain version of the time-domain formulation found in [3]. The number has been chosen so that the variables and the coefficients of the matrix have the same size, leading to a better conditioning of the matrix.…”

Parallelization of the boundary element method for the modelling of large electromagnetic scattering problems

“…By combining the formulations which are obtained at points located on inside and outside regions, we have then these following expressions [3]: & for the dielectric. The equations are combined so that the term VGo-VGI appears: all terms of the equation are then absolutely integrable.…”
