Modeling objects with multilayered coatings with High Order Impedance Boundary Condition

This paper deals with the use of High Order Impedance boundary condition (HOIBC) in 3DMoM codes to improve the accuracy of the Standard Impedance Boundary Condition (SIBC) when modeling multilayer coatings. HOIBC formulation for 3DMoM codes has been presented in [1–3], together with validations. In this paper, we give validations of the HOIBC for multilayered coatings that show the improvement in accuracy obtained over SIBC computations.
