  • Abstract
    We present a new technique of incorporating macromodels into the frequency domain formulation of grid based methods. Unlike previous methods, the new scheme does not introduce any frequency dependent elements into the system matrix and thus can be used in the analysis of resonator problems. Numerical results show an increase in accuracy of computations in a wide frequency range while convergence properties of the underlying matrix eigenvalue solver are not affected.
