(color online) (a) Electric field and (c) magnetic field distributions at resonance. Panels (b) and (d) are the enlarged views around the slit and graphene in panels (a) and (c), respectively. Black rectangles mark the areas where metal exists. The white arrows in panel (c) indicate schematically the current flow in the metals.
