A surface/surface formulation was used in  to analyze the scattering from periodic planar coated strips. This paper is an extension of  where a combined volume/surface formulation has been used to solve the same problem. This formulation can be applied to problems which involve an inhomogeneous dielectric medium or/and a thick dielectric which requires the inclusion of the edge currents which were neglected in  as a simplification. Results obtained using the volume/surface formulation have been compared with the results published in  which were obtained using a surface/surface formulation.
