In optics, the Ewald-Oseen extinction theorem underlies the field's standard understanding of how light scatters, refracts, reflects and diffracts when it meets matter. It's named for Paul Peter Ewald and Carl Wilhelm Oseen, who proved versions of the theorem for crystalline and isotropic media respectively, in 1916 and 1915. The theorem originally covered scattering by isotropic dielectric objects in free space, and its scope has since been extended to a much wider range of bianisotropic media.
Facts
StatementIn optics, a theorem that underlies the common understanding of scattering, refraction, reflection and diffraction. Originally it applied to scattering by isotropic dielectric objects in free space, and its scope was later extended to a wide variety of bianisotropic media. 1 Partially Attested
