Efficient integral equation based solvers for modelling antennas mounted on electrically large and complex platform

Efficient modelling of the performance of antennas mounted on electrically large and complex platform is essential for practical antenna design with considering environment effect and yet a challenging area in electromagnetic compatibility (EMC) assessment. This paper presents our team efforts to tackle this problem through three ways: (1) fast full-wave simulation code development with technical core of surface-wire integral equation (SWIE) and precorrected-FFT (P-FFT) algorithm; (2) efficient hybrid low and high frequency modelling capability with technical core of a newly developed efficient iterative method of moments (MoM) - physical optics (PO) hybrid method; (3) hardware accelerated simulation capability with technical core of parallel P-FFT implementation for solving SWIE on GPU. Successful simulation of many standard benchmarks and realistic targets extensively validates the proposed three techniques.
