from Umul. [ 14 ] Although this field has the same discontinuities, with the total GO wave at the transition boundaries, since the subtraction operation, the location of the incident GO wave is reversed. The scattered GO field can be obtained by subtraction of Equation (10) from Equation (28) as follows:

{\overset{H}{true}}_{normalSGO} = {\overset{e}{true}}_{z} Γ H_{0} H_{0}^{(2)} false({kR}_{i} false) U false(ξ_{-} false) + {\overset{e}{true}}_{z} Γ H_{0} H_{0}^{(2)} false({kR}_{r} false) U false(- ξ_{+} false)

using the relation of Γ = T − 1 and the expression U ( x ) = U ( −x ) − 1.…”

An integral theory that is associated with the scattered fields is considered for the solution of H-polarized line source diffraction by a conductive half-plane, which is surrounded by an anisotropic plasma. As the anisotropy does not affect an E-polarized incident wave, only one polarization case is considered. The cold plasma medium is characterized by the dielectric tensor. The constant external magnetic field producing the anisotropy in a cold plasma is applied parallel to the edge of the half-plane. The total, scattered, and diffracted waves are derived in terms of the Fresnel functions. Therefore, finite magnitude values at the transition boundaries are obtained. The wave behaviours are investigated numerically for different quantities of the medium.
