Accuracy verification of the antenna electromagnetic environment simulation with hybrid method

Various numeric methods exist for analyzing electromagnetics problems with their own advantages and disadvantages. MoM is suitable for scattering analysis in low-frequency or of targets in resonance region. For ultra large systems, MoM+PO and MLFMA are respectively available for problems with different structures and accuracy requirement. This paper simulates the electromagnetic environment (EME) of antennas with focuses on analyzing ultra large systems with parallel-MLFMA. Conducting some comparisons with data from both literatures and measurements, we aim to evaluate the accuracy of the calculating result of the antenna near-field with numerical method. According to these contrasts, it can be said that our computed data and the theoretical/measured data of antennas near-field agree well.
