    Abstract
  • An efficient hybrid approach, which combines the full-wave and high-frequency method, i.e., the multilevel fast multipole algorithm (MLFMA) based volume-surface integral equation (VSIE) and the modified surface integration (MSI) method, was proposed to analyze the electromagnetic characteristics of the electrically large radome-antenna system in receiving mode. The MSI method determined the transmitted field distributions through the radome firstly and treated the fields as the excited source of the antennas, and then the MLFMA accelerated VSIE solver was used to analyze the antennas accurately. The method employed spherical harmonic expansion, preconditioner and hybrid parallel techniques to further improve the calculation efficiency of the algorithm. This new IE/MSI+MLFMA method has reasonable accuracy and dramatically reduces the computational time and improves the efficiency when compared to the conventional full-wave numerical methods, and produces fast and efficient simulation of electrically large antenna-radome system.
