“…The MoM results in a dense impedance matrix, and the MoM matrix is computationally intensive especially for frequency-sweeping cases. The polynomial interpolation and extrapolation methods [3][4][5][6][7][8][9][10][11][12]19], the rational polynomial approaches [13][14][15][16][17][18]20], and other techniques [21][22][23][24][25][26][27] have been proposed for fast generating the MoM matrices, the current distributions, and the radar-cross-section (RCS) results over a frequency band. The quadric polynomial interpolation method originally adopted in [3] was improved by extracting the dominant phase term [4].…”

The inter/extrapolation accuracy of the cubic polynomial method has been improved by optimizing three frequency samples for frequency-sweeping in the method of moments (MoM). In the method, the frequency samples are optimized by minimizing the global maximum of the polynomial component at the stationary points and two terminal points of the frequency band. The optimal frequency samples can be expressed as analytical forms of the two terminal points. Numerical examples are presented to validate the proposed method through comparison with the Padé approximation.

In this article, wire antennas installed on electrically large structures are modeled by surface-surface configuration. The surface-surface configuration is applied to the hybrid method of moments-physical optics (MoM-PO) to solve electromagnetic radiation problem of wire antennas mounted on electrically large conducting platform. Numerical results for the arbitrary shaped perfectly electric conducting are considered. Compared with the wire-surface configuration, the surface-surface configuration is easy to ensure the current continuity at the junction and maintain the required good accuracy. Additional complex basis functions are not required in surface-surface junction model compared with wire-surface junction model.
