Schematic of the multilayer structure consisting of a finite-period PC atop a semi-infinite PC.
Normal reflectance spectra in the vicinity of the stop band for: PC1 with six unit cells (top panel); PC2 with 30 unit cells (middle panel); the structure composed of PC1 stacked atop PC2 (bottom panel). The geometric parameters are set to be and with for both PCs.
Contour plot of the reflectance with respect to the angular frequency and incidence angle. The geometric parameters are the same as Fig. 2. The brighter color in the color bar located beside the contour plot indicates the higher reflectance value.
The square of the displacement field, normalized by the value at , inside the structure at normal incidence with (bottom panel) or without (top panel) an interfacial wave.
