Abstract

Coating of the conducting objects with thin layers of magnetic materials is used to reduce, significantly, the back scattering from axi-symmetric objects. The concept of the impedance boundary condition (IBC) is used to solve the problem. The present formulation predicts an accurate value of surface impedance from the equivalent volume magnetic current of the magnetic material layer. The IBC concept is used to predict the coating material permeability and thickness in order to reduce the backscattering radar cross section (RCS). The numerical solution is verified by comparison with numerical solutions based on the exact boundary conditions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
