A Note on the Integral Equations for the Scattering of a Plane Wave by an Electromagnetically Permeable Body

Abstract

ABSTRACT The integral equations governing the scattering of a plane wave by an electrically and magnetically permeable obdy are investigated by two alternative methods. In the first method, the homogeneous wave equations for Ē are integrated with the aid of the free-space dyadic Green's function that yields directly an integral equation for Ē. In the second method the equivalent polarized currents are introduced as previously done by Harrington that yields two coupled integral equations for Ē and . By eliminating between these two equations one obtains the same integral equation for Ē as derived by the first method.
