abstract

  • In this paper we consider implementations of the FMM and AIM compression schemes to speed-up the solution time associated with finite element-boundary integral systems. Of particular interest is the analysis of cavity backed antennas which may possess fine details as is the case with slot arrays, spirals, log-periodic and other broadband antennas. In those cases, the computational demand for the boundary integral is large in comparison to that of the finite element volume subsystem and therefore a fast integral method is attractive for speeding-up the iterative solution algorithm. We will present the CPU improvement using AIM and FMM with particular emphasis on the capability of each method to handle these types of antenna problems.
