(a) versus the angle of incidence for structure without graphene layers (solid curve), with graphene layers of which  eV (dashed line),  eV (dash-dotted line),  eV (dash-dot-dotted line),  eV (bold dashed line), and  eV (bold dash-dotted line). (b) versus the incident intensity corresponding to the five situations mentioned in (a).
