FIG. 1.

Band structure of a 1D MD stack. The gray zones represent the allowed bands. The black line denotes the light line of dielectric. The result obtained from the analytical criteria is between the gray dashed lines. , , , and .

FIG. 2.

Dispersion relation of a MDM waveguide. The black line is the light line of dielectric. The lower gray line denotes the fundamental SPP modes. The first-order guided modes and SPP modes coexist in the lower dashed line. The higher gray (dashed) line denotes the second (third)-order guided modes.

FIG. 3.

Normal incidence transmittances of a 4.5-period stack with thick on the entrance and exit faces (the solid line) and of a same structure except the metal is described by Drude model (the dashed line).
