| Abstract: | In order to investigate the influences of the dielectric constant on the plasma photonic crystals,the dispersion relation of one-dimensional plasma photonic crystals has been studied by solving a stationary Maxwell wave equation with a method analogous to Kronig-Penney's problem in quantum mechanics.The results showed that the dielectric constant affected greatly on both of the band gap width and the band edge frequencies.The bandgaps became more obvious with an increasing of the dielectric constant,and the changes of the first and second band gap widths were different.In addition,the cut-off frequency of this plasma photonic crystal as well as the edge frequency of the second band gap was decreased with an increasing of the dielectric constants. |
