Abstract
In this paper, the combination of FMIR-MoM with barycentric subdivision-based quadrature is utilized to analyze the Wideband RCS of the PEC objects. By using the FMIR-MoM, the electromagnetic properties over a wide frequency band can be quickly obtained. In this method, smaller frequency band division is not needed while it is required in the interpolation techniques. The memory requirement is comparable to the later ones. However, the special treatment is yet needed when dealing with the singularity term. The barycentric subdivision-based quadrature is applied in impedance fill-in, in which the singular integral can be avoided. Two numerical examples are included to test the accuracy.
