ELECTROMAGNETIC SCATTERING FOR OBLIQUE-INCIDENCE ON IMPEDANCE BODIES OF REVOLUTION

Combined field integral equations for the surface currents induced by an obliquely incident wave on a rotationally symmetric body are consid ered, The relative surface impedance is independent of the azimuthal a ngle, but mag vary along the profile of the scatterer in any plane con taining the axis of symmetry; the currents are conveniently expressed in terms of Fourier series of uncoupled terms in the azimuthal angle, Simple integral expressions for the far field are given and a computer code is described and tested on a variety of scatterers, Geometry of scatterer, surface impedance and Fourier harmonics of induced currents are described by splines, The results are in agreement with physical interpretation.
