Abstract :
The SEMN method was previously introduced by Tavakkol-Hamedani and Tavakoli (see IEEE AP-S Symposium, p.2358-61, 1997) and general formulas and derivations for the analysis of complex structures were presented. In order to eliminate singularities in the source region, closed-form expressions for computation of the self-coupling matrices of rectangular and circular segments with uniform equivalent electric and magnetic surface currents are derived. We also analyzed a finite microstrip antenna and obtained good agreement between the theoretical and experimental results.
