Abstract :
This paper illustrates the capability of SR3D software to rigorously analyse 3D radiating structures including wires (thin or thick), dielectric parts, and finite ground planes. The analysis method is within the class of boundary element methods (BEM) and uses an integral equation formulation (combined field integral equation CFIE) to solve electromagnetic scattering problems. It includes a variational approach based on Rumsey´s (1954) reaction concept. The problem is numerically solved with a surface finite element method: surfaces of 3D conducting objects and interfaces between dielectric domains are meshed using surface triangular patches.
