article description
The implication of multilevel fast multipole algorithm (MLFMM) is applied to the analysis of large antenna array of the dual-polarized log-periodic dipole antenna in the presence of dielectric half-space and arranged in a random array configuration for Square Kilometer Array (SKA) radio telescope. The MLFMM is applied to accelerate the matrix-vector product operations. The findings are compared with the results obtained by standard MoM solver. Numerical results are given to demonstrate the accuracy and capability of this algorithm.
