Characteristic mode analysis : ウィキペディア英語版 | Characteristic mode analysis
Characteristic mode analysis is a method used in electromagnetics to solve for currents and fields generated by a scattering object of any size or material.〔 == Background ==
When an electromagnetic wave is scattered by an object, currents are induced on said object which subsequently re-radiate 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 that the original incident wave was radiated.〔〔
