Comparison of four MoM formulations when solving electrostatic problems where rotational symmetry is exploited

This paper presents results for numerical analysis of three electrostatic problems by using four MoM (method of moments) formulations while exploiting the rotational symmetry of the analyzed structures. These results are mutually compared, but also compared to the results obtained by the electrostatic solver where rotational symmetry is not considered. It is observed that exploiting the rotational symmetry reduces the number of unknowns needed for the analysis.
