Antiradar protection of nonplanar surfaces

A coating making a plane surface invisible for radar does not protect a nonplanar surface if its radius of curvature is not sufficiently large as compared to the wavelength. Parameters of the coating protecting a nonplanar surface depend on frequency and the shape of the surface. Two types of coatin...

Description
Summary:A coating making a plane surface invisible for radar does not protect a nonplanar surface if its radius of curvature is not sufficiently large as compared to the wavelength. Parameters of the coating protecting a nonplanar surface depend on frequency and the shape of the surface. Two types of coatings are considered: the generally accepted impedance coatings and coatings formed by a dielectric layer (film). Physical processes occurring in such coatings and providing antiradar protection are described. The parameters of the coating for a cylinder and a sphere are found from transcendental equations and, for an arbitrary body, from a system of integral equations.
