Abstract :
This paper briefly introduces the MoM-based computationally efficient technique combining the domain decomposition and Z matrix interpolation supported by an adaptive frequency sampling for the wide-band performance evaluation of antennas/scatterers. Numerical examples demonstrate the usefulness and effectiveness of the technique and the offered saving in terms of both CPU time and memory storage relative to the direct MoM approaches.
