Uittreksel

An enhanced version of the Linear Embedding via Green's Operators (LEGO) method is introduced to analyse complex 3-D metallic structures. In order to change certain parts of a complex structure without recalculating the parameters of the entire structure we have applied a domain-decomposition method to divide the structure into segments. The segments are then associated with sub-domains, also known as bricks, to separate them from the rest of the structure. The bricks are formed in such a way to close the space around the object and each brick is analysed separately before we combine them together to obtain the parameters of the entire structure. In this way we also increase computational efficiency, distinguish between parts with different dynamic mesh range and coupling level. To ensure connectivity between all the parts of a complex structure inside different bricks we have introduced ports. Each port represents a set of Rao-Wilton-Glisson (RWG) functions associated with a pair of triangles located on the metallic structure and halved by two brick boundaries. We have used the Electric Field Integral Equation (EFIE) together with the Method of Moments (MoM) to solve for each brick and for the entire structure. Comparisons between the direct solution, which solves EFIE directly over the structure, and the LEGO approach are shown to prove the concept.
