Scattering Analysis of Thick Wires with the MoM using Macro Basis Functions

• This work is concerned with the analysis of scattering by conducting wires connected to conducting structures, using the method of moments (MoM). Based on thin-wire assumptions, low numbers of degrees of freedom (DoFs) are required by typical exact-kernel thin-wire MoM solvers, for accurate analysis. However, the thin-wire assumptions break down when the wire diameter becomes appreciably large in terms of the wavelength. An approach based on macro basis functions (MBFs) for wire current representation is outlined, aimed at extending the wire thickness range of accurate analysis, while maintaining a low number of DoFs similar to that of thin-wire formulations. Preliminary results demonstrate the effectiveness of the MBF approach.
