Abstract
In case of non-spherical particles, by considering the elements of the amplitude matrix J, the form of the optical theorem for the cross-section is obtained in a general way which is faster than how is shown in usual textbooks. It takes into account polarization of incident radiation. Polarized radiation scattered in the forward direction by a thin layer of the medium is added to the incident plane wave. Interference leads to the optical theorem. Dichroism can be avoided by considering two modes of polarization, which can be defined from the elements of the J matrix. In this paper: upper-case bold symbols denote vectors or matrices; lower-case bold symbols denote unit vectors.
