High-order Treatment of Junctions and Edge Singularities with the Locally-corrected Nyström Method
关键词:
Edge singularities, high order representations, junction conditions, singular basis functions摘要
High order techniques are known to be effective for the electromagnetic analysis of smooth structures. In the following, high order representations developed for the current density at edges and junctions are incorporated into the locally-corrected Nyström method. Conducting structures used for purposes of illustration include a strip, a structure with three fins and a junction, and a hexagonal cylinder. Results suggest that the accuracy of the numerical results obtained with the new approach is comparable to that obtained for problems with smooth surfaces.
