RCS and Near Field of a Dielectric Sphere

Calculate the radar cross section and the near field inside and outside of a dielectric sphere using the surface equivalence principle (SEP).

The bistatic radar cross section for sphere1 is computed by:

(1) σ ( b i s t a t i c ) = lim r [ 4 π r 2 E s 2 E i 2 ] .
