Abstract :
The fast analysis of large antenna phased arrays remains an interesting and challenging problem. This paper presents an approach to accelerate the MOM by employing a DFT (discrete Fourier transform) representation for the unknowns of conventional MOM. Such an approach combining DFT with MOM is called DFT-MoM. The DFT-MoM employs the coefficients of the DFT representation as the new unknowns and solves for the DFT coefficients. The MOM unknowns are then obtained subsequently.
