Abstract

- Two novel formulations of the reaction are derived. The formulations decompose the electromagnetic fields in scattered components based on the location of the sources of the scattered fields. It is shown that some of the scattering components do not contribute to the reaction. The novel formulations of the reaction are derived by excluding these noncontributing components from the classical reaction formulations. The correctness of one of the formulations is verified with a numerical example. It is observed from one of the novel formulations that the first-order scattered fields do not contribute to the reaction. This result legitimizes the approximation to neglect multiple scattering, which is a common assumption when using reaction theorems. The novel formulations are also important for a conceptual understanding of the reaction.
