The T-matrix or transition matrix is well known in the quantum theory of scattering [ 56 ] where one also uses the Heisenberg S-matrix connected with the T-matrix by the relation . In contrast to the coordinate representation in the integral equation method, where the scattered and incident fields are connected by the Green function, the T-matrix connects the coefficients of the expansions of the scattered and incident fields in terms of a complete system of the vector basis functions. ...
