Analysis of scattering by means of atomic model

An atomic model has been proposed to analyze scattering problems by a diele ctric cylinder of arbitrary cross section. The advantages and differences f rom the usual method of moments are: (1) the field exiting an atom is that due to all the sources other than that atom, (2) the cause-and-effect relat ionship is clear and no singularity occurs, (3) various scatterers, from di electrics to conductors, can be handled, (4) dielectric scatterers mixed wi th conductors can be treated, (5) all the information about the inhomogenei ty of the scatterer appears only on the diagonal of the matrix, and (6) the theory smoothly connects with the atomic theory, which is educationally de sirable.
