The replica material used in this study is Polydimethylsiloxane. The enlargement of replica compared to original size is 2.34%. Since PDMS is transparent, a layer of metal should be sputtered on its surface to measure optical characteristic, however the accuracy will be affected by the metal coated. The result assumes that Sternocera aquisignata, Chrysochroa rajah and Catoxantha opulenta may have one-dimensional photonic crystal structure. The fabrication of quasi-structure with elytra from Buprestid can promote the applications in the field of photonic structure and optical components.

Some basic properties of σ- LFSR over F4 are studied, such as nonlinearity, cycle structure distribution of state graph, the largest period and counting problem related. The conclusions are as follows:The coefficient ring of σ-LFSR is isomorphic to the matrix ring over F,. The cycle structure of σ- LFSR is consistent with that of the determinant of the corresponding polynomial matrix if and only if the feedback polynomial of - LFSR does not contain nontrivial factor over F2,.
