Memory-efficient, full-wave analysis of waveguide scattering parameters for multiple reflector feeds mounted on electrically large satellite platforms

A Higher-Order Multilevel Fast Multipole Method (HO MLFMM) is presented for the efficient calculation of waveguide scattering parameters in cases where several reflector feeds are mounted on electrically large satellite platforms. The efficiency is obtained by: 1) using a Block Krylov method for solving the HO MLFMM problem for the required large number of right-hand sides and 2) implementing an out-of-core solution, taking into account the fact that the memory distribution of HO MLFMM is different from the standard low-order MLFMM.
