forbidden band造句

1、Using this method, the forbidden band characteristics of several typical two-dimensional photonic crystals are discussed.

2、As a new kind of man-made structure function material, photonic crystals could realize thermal infrared camouflage because of its high-reflection photon forbidden band.

3、The influence of three main factors such as lattice structure, packing ratio and dielectric constant ratio on complete forbidden band of 2-d air cylindrical photonic crystal is studied.

4、Silicon and germanium, for instance, have forbidden bands whose widths are 1.1 and 0.65eV, respectively.
