Abstract

The electromagnetic dual-primal finite element tearing and interconnecting (FETI-DPEM) method is a non-overlapping domain decomposition method developed for the finite element analysis of large-scale electromagnetic problems. The method is particularly suitable for simulating large finite arrays because the geometrical repetitions of an array structure can be exploited to further enhance the computation performance. The method has been applied to the simulation of phased-array antennas in addition to other finite array structures. This paper presents the first experimental validation of this method for the simulation of a highly complicated realistic phased-array antenna. The antenna geometry is described in detail and the comparison between the simulated solution and experimental measurement is presented.
