| Abstract: | Research of the first band gap characteristics of photonic crystal is very important for the design transmission devices. The first band gap characteristics of two - dimension cylinder lattice photonic crystals with the SIC, Si, Ge, InSb and HgTe semiconductor material were calculated by MATLAB based on transmission theory of electromagnetic wave. The results showed that photonic crystals with the larger dielectric constant have the wider band gap at the different the filling rates. The upper and lower boundary frequency of the first band gap trundled up, the width of the first band gap increased with increasing the filling rates. All these results can provide theoretic basis for photonic crystal devices design. |
