“…The volumic surface integral equation (VSIE) 14–17 and the surface integral equation (SIE) 1,4,13,18–22 in conjunction with the method of moments (MoM) are the most powerful techniques to solve this problem numerically, each one has its advantages and its disadvantages depending on the considered problem 23–25 …”

In this paper, we propose a new method to approximate operators resulted from solving the scattering Problem in electromagnetism by dielectrically coated conducting bodies, using integral equations and high order impedance boundary condition. We introduce the variational Problem and we prove its well‐posedness. After discretization, we find that operators arising from the high‐order impedance boundary conditions are not well‐defined. We present the new theoretical approach and highlight its potential through numerical experiments.
