Abstract

A modular approach is proposed to combine MoM and FEM for the fast analysis of finite arrays. The hybridization of MOM with FEM is obtained by using FEM to produce primary and secondary Macro Basis Functions (MBFs). A special mesh truncation technique based on domain decomposition is used. Once the MBFs are obtained, the finite array is solved via a reduced MOM problem with the MBFs so obtained as basis functions. The implementations of MOM+MBF and FEM methods are made in separate codes using surface triangular, and volumetric tetrahedral meshes, respectively.
