WebThe scattering of electromagnetic eld is an important topic. A source radiates a eld, and ultimately, in the far eld of the source, the eld resembles a plane wave. When a plane wave impinges on an object or a scatterer, the energy carried by the plane wave is de ected to other directions which is the process of scattering. predisposed state of mind
