Аннотация:The optical theorem is generalized to the case of excitation of a local body by a multipole. To compute the extinction cross-section, it is sufficient to estimate the derivatives of the scattered field at the single point where the multipole is located. The relation obtained in this paper makes it possible to test software modules developed for analysis of wave scattering by a nonabsorbing obstacle.
