Characteristic Mode Analysis is a method used in electromagnetics to solve for currents and fields generated by a scattering object. The object can be any size or material.
When an electromagnetic wave is scattered by an object, currents are induced on said object, which subsequently reradiate electromagnetic energy. The structure of the currents (and fields) are unique to the physical dimensions of the scatterer and incident frequency of radiation. From this perspective, a scatterer can be viewed as a parasitic antenna that radiates electromagnetic radiation in the same way as original incident wave was radiated.
