RCS of creeping wave for shadow region of wing leading edge

Based on geometric diffraction theory,Finite difference in time domain is used to study the scattering and diffraction of electromagnetic waves on the surface of conductor sphere,to analyze the properties of creeping waves on the conductor surface and to calculate the scattering features of the electromagnetic waves on the metal sphere with different conductivities,buried in the sandy soils.

To the low RCS target, the effect of creeping wave is remarkable and larger than that of facets and wedges in some cases.
