3D MoM computations with high order impedance boundary condition

This paper deals with the use of High Order Impedance boundary condition (HOIBC) in 3D MoM codes to improve the accuracy of the Standard Impedance Boundary Condition (SIBC). There have been very few reports of the implementation and validation of HOIBC in 3D MoM codes ([1], [2]). We give validations of the HOIBC obtained with a 3D MoM code that show the improvement in accuracy obtained over SIBC computations.
