Derivation of extended boundary condition method from general definition of T-matrix elements and Lippman-Schwinger equation for transition operator

摘要

Waterman's surface-integral expressions for the T-matrix elements are derived on the basis of the quantum-mechanical potential scattering approach in electromagnetic scattering problem. We use general definition of the elements of the T-matrix as the matrix elements of the dyadic transition operator and Lippman-Schwinger volume integral equation for the dyadic transition operator. The interrelations of the Q- and Waterman's T-matrix with the transition operator are shown. (C) 2007 Elsevier Ltd. All rights reserved.
