Application is presented of the Synthetic Function eXpansion (SFX) method to the accurate analysis of devices that incorporate microstrip‐technology electromagnetic band‐gap structures of large but finite size. The strong reduction of the dimension of the system matrix achieved employing the SFX technique reduces the solution time and the memory occupation, making it possible to analyze large structures on standard computational hardware. Experimental verification confirms the validity of the approach. © 2009 Wiley Periodicals, Inc.
