FIG. 1.

The one-dimensional PC plate with a substrate. The PC layer consists of the material A (silicon) with the width and the material B (tungsten) with the width , and the lattice spacing is , and the filling rate is defined by . The values of , , and are fixed at , and 0.5, respectively, throughout the paper.
