(color online) (a) Emissivity spectrum for the grating with h = 6.0 μm and f = 0.7. i = 1,2,3 corresponds to the 1 , 2 , and 3 order of the SPSW mode. j = 1 represents the 1 order of the SPP resonance. The field intensity distributions are shown: (b) for i = 1, (c) for i = 2, and (d) for i = 3. The white circles mark the positions of the nodal points.
