Generalized optical theorem for reflection, transmission, and extinction of power for electromagnetic fields.
We present a generalization of the optical theorem for electromagnetic fields. This result is used to obtain the power extinguished from a field by a scatterer contained in a dielectric half space. Applications to microscopy and tomography are described.
