Image of FIG. 1.
FIG. 1.

(a) and (b) show the dependence of TM polarized reflectance and reflection phase shift on frequency, respectively, in the PC with dielectric rods in an air background; (c) and (d) show the dependence of TM polarized reflectance and reflection phase shift on frequency, respectively, in the PC with air rods in a dielectric background. The dielectric index of refraction is , , and . Points A and B are the lower edge of the first stop band in (b) and (d), respectively. (e) shows the electromagnetic field Bloch modes at point A and B in unit cells. The dashed lines on the left side of the cells denote the reflection interface.

FIG. 3.

(a) and (b) show the dependence of TM polarized reflectance and reflection phase shift on frequency, respectively, in the PC with dielectric rods in an air background. The dielectric index of refraction , , and . (c) shows the phase regions of different order stop band with different rod radii, where the phase regions are denoted by two points linked by line. The two points indicate the upper and lower edges of each stop band.

In (b), (c), (d), and (e), the solid line denotes TM wave, dotted line denotes TE wave, and dashed-dotted line denotes . For , , and , the reflectance (b) and reflection phase shift (c) vary with frequency, and the PC can be regarded as a half-wave plate in the shaded area. For and , the reflectance (d) and reflection phase shift (e) vary with frequency, and the PC can be regarded as a quarter-wave plate in the shaded area.
