Extensive numerical resu lts for electromagnetic scatterin g fro m spheres are p rese nted in grap hi cal fo rm. To simulate various types of coatings, the su rface impedance of the sphere is a speeifi ed comp lex fun ction. It is s hown conclusively that the forward scatter ing lobe is almost in dependent of the characteri stics of the coati ng . On the othe r hand , t he backseattering a nd side scatterin g are p rofo undly mod ifi ed by changes in the effective impedance of the coating.

The problem of electromagnetic scattering by homogeneous spheres with relative impedance equal to unity is considered. From the Mie series expression for the induced internal fields, the details of the condition responsible for producing a null in the backscattering cross section are deduced. The existence of this null is attributable solely to destructive interference, regardless of frequency, and is valid for either lossy or lossless media. The returned signal in the vicinity of the null is determined from numerical computation of the bistatic cross sections.
