Using Multiple-precision Arithmetic to Prevent Low-frequency Breakdowns in the Diagonalization of the Greens Function
Multiple-precision arithmetic(MPA)is used to prevent low-frequency breakdowns in the diagonalization of the Greens function that is required to implement the multilevel fast multipole algorithm(MLFMA).The breakdown problem is considered at a numerical level,where rounding errors are reduced by increasing the precision as much as required.Using MPA seems to provide a direct solution to low-frequency breakdowns of the standard diagonalization,which may lead to straightforward implementations of broadband MLFMA.
