Electromagnetic scattering by an exponentially inhomogeneous plasma sphere

The mathematical analysis of electromagnetic wave scattering by radially inhomogeneous spherical objects is treated. Numerical integration of the differential equations for the separated radial wave functions has been carried out for the case of a plasma with an exponential electron density gradient, Parametric calculations of bistatic scattering have given many interesting results. The range of validity of the Born approximation has been demonstrated by comparing it with computed results.
