Аннотация:Based on integral transforms for wave fields, we obtain a generalization of the
optical theorem for the case in which a local inhomogeneity is excited by a multipole source
of arbitrary order. This generalization permits determining the total scattered and absorbed
energy analytically by computing the derivatives of the scattered field at a single point. This
relation can be used to compute the absorption cross-section in problems related to plasmonic
structures and also to test computer modules when multipole radiation is scattered by transparent
bodies.
