A full-wave computational model for electromagnetic scattering of conically incident plane waves with arbitrary polarization is proposed for a multilayered structure (laminate) made of dielectric slabs wherein periodically arranged circular cylinders are embedded. An electric field is considered as the incident wave with arbitrary polarization. The magnetic field produced by the incident wave is obtained with Maxwell’s equations. Both the transverse electric and magnetic field components are used for mode-matching at the boundary for calculating the scattering matrices. Power reflection and transmission coefficients follow from Poynting’s theorem. This work is a first step toward the Green’s function of the structure, in view of imaging a possibly damaged laminate
