Abstract :
Full-wave electromagnetic analysis of complex interconnects with efficiently controlled accuracy is performed via higher-order (HO) boundary element Locally Corrected Nyström (LCN) method. To guarantee desired accuracy of electromagnetic analysis in solution of the associated large-scale problem the LCN discretization of the integral equation is accelerated with error-controllable Multi-Level Fast Multipole Algorithm. The HO LCN solution is compared against traditional Rao-Wilton-Glisson Method of Moments solution of the combined field integral equation. It is shown that HO LCN scheme reaches desired precision of full-wave characterization with exponentially lower computational resources.
