K. Manabe et Y. Miyazaki, A 3-D BOUNDARY-ELEMENT ANALYSIS OF EM WAVE SCATTERING BY A PERFECTLY CONDUCTING BODY WITH EDGES AND CORNERS, IEICE transactions on electronics, E78C(10), 1995, pp. 1460-1464
A numerical scheme to analyze a three-dimensional perfectly conducting
body that has edges and corners is presented. The geometry of the bod
y can be arbitrary. A new formulation using boundary element method ha
s been developed. This formulation allows that a scatterer has edges a
nd corners, where the behavior of the electromagnetic fields become si
ngular.
