Abstract

Scattering of electromagnetic waves by perfectly electrical conducting (PEC) cylinder, coated with chiroferrite medium, is investigated under the oblique angle of incident. The coated PEC cylinder is wrapped with perfectly conducting sheath helix structure. For this structural configuration, the bi- and the mono-scattering echo widths are computed numerically while assuming the incident wave with parallel polarization. The roles of pitch angle (of sheath helix structure) and the material parameters on the echo width are analyzed. The obtained results for scattering echo widths are compared with those achieved when the PEC cylinder is coated with simply chiral material. It is found that the chiro-ferrite coating causes larger scattering of waves than the situation when the PEC cylinder is coated with simply chiral medium. Furthermore, a parallel orientation of the helix structure results in larger echo width.
