Abstract
A novel high-order impedance boundary condition (HOIBC)-enhanced integral equation solver is proposed for the analysis of electromagnetic scattering from bodies of revolution (BoRs) with low-index coatings. The HOIBC is specifically introduced to improve the accuracy of modelling the low-index coatings. The surface electric currents, magnetic currents and surface electric fields are all expanded using BoR basis functions in the proposed method (BoR-HOIBC). Only electric currents are solved in the final system by invoking the relationship between the electric and magnetic currents, as well as between the electric currents and fields, as dictated by the HOIBC. The proposed solver is rigorously validated through comparisons with Mie series solutions and the full-wave methods. Numerical results demonstrate that it achieves significant improvements in both efficiency and accuracy.
