This letter discusses the connection of a dynamic electromagnetic variable, the radar cross section, and a static parameter, the polarizability. It is shown that with full-wave electromagnetic computation of the scattering of a sphere, its static response can be enumerated with good accuracy with remarkably few unknowns. The result suggests that the code can be used with success to also calculate the polarizability of objects with other shapes. This is important since the polarizability of complex objects has been a difficult computational problem to tackle.
