    • Preconditioning techniques in the analysis of finite metamaterial slabs 

      Úbeda Farré, Eduard; Rius Casals, Juan Manuel; Romeu Robert, Jordi (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-01-31)
      Article
      Accés obert
      In the method of moments (MoM) electric field integral equation (EFIE) analysis of slabs of metamaterials, we show that a left-preconditioning scheme by blocks gathering interactions between basis functions belonging to ...
